PRODUCT DESCRIPTION

TEMP

The AD780 is an ultrahigh precision bandgap reference voltage

which provides a 2.5 V or 3.0 V output from inputs between

4.0 V and 36 V. Low initial error and temperature drift com-

bined with low output noise and the ability to drive any value of

capacitance make the AD780 the ideal choice for enhancing the

performance of high resolution ADCs and DACs and for any

general purpose precision reference application. A unique low

headroom design facilitates a 3.0 V output from a 5.0 V 10%

input, providing a 20% boost to the dynamic range of an ADC,

over performance with existing 2.5 V references.

PRODUCT HIGHLIGHTS

1. The AD780 provides a pin-programmable 2.5 V or 3.0 V

output from a 4 V to 36 V input.

The AD780 can be used to source or sink up to 10 mA and can

be used in series or shunt mode, thus allowing positive or nega-

tive output voltages without external components. This makes it

suitable for virtually any high performance reference application.

Unlike some competing references, the AD780 has no “region

of possible instability.” The part is stable under all load condi-

tions when a 1 µF bypass capacitor is used on the supply.

2. Laser trimming of both initial accuracy and temperature

coefficients results in low errors over temperature without the

use of external components. The AD780BN has a maximum

variation of 0.9 mV from –40°C to +85°C.

3. For applications requiring even higher accuracy, an optional

fine-trim connection is provided.

4. The AD780 noise is extremely low, typically 4 µV p-p from

0.1 Hz to 10 Hz and a wideband spectral noise density of

typically 100 nV/√Hz. This can be further reduced if desired,

by simply using two external capacitors.

A temperature output pin is provided on the AD780. This pro-

vides an output voltage that varies linearly with temperature, al-

lowing the AD780 to be configured as a temperature transducer

while providing a stable 2.5 V or 3.0 V output.

5. The temperature output pin enables the AD780 to be config-

ured as a temperature transducer while providing a stable

output reference voltage.

The AD780 is a pin-compatible performance upgrade for the

LT1019(A)–2.5 and the AD680. The latter is targeted toward

low power applications.

The AD780 is available in three grades in plastic DIP, SOIC,

and cerdip packages. The AD780AN, AD780AR, AD780BN,

AD780BR, and AD780CR are specified for operation from –40°C

to +85°C.

THEORY OF OPERATION

APPLYING THE AD780

Bandgap references are the high performance solution for low

supply voltage and low power voltage reference applications. In

this technique a voltage with a positive temperature coefficient is

combined with the negative coefficient of a transistor’s Vbe to

produce a constant bandgap voltage.

The AD780 can be used without any external components to

achieve specified performance. If power is supplied to Pin 2 and

Pin 4 is grounded, Pin 6 provides a 2.5 V or 3.0 V output de-

pending on whether Pin 8 is left unconnected or grounded.

A bypass capacitor of 1 µF (V_INto GND) should be used if the

load capacitance in the application is expected to be greater

than 1 nF. The AD780 in 2.5 V mode typically draws 700 µA of

Iq at 5 V. This increases by ~2 µA/V up to 36 V.

In the AD780, the bandgap cell contains two npn transistors

(Q6 and Q7) which differ in emitter area by 12ϫ. The differ-

ence in their Vbe’s produces a PTAT current in R5. This in

turn produces a PTAT voltage across R4, which when com-

bined with the Vbe of Q7, produces a voltage Vbg that does not

vary with temperature. Precision laser trimming of the resistors

and other patented circuit techniques are used to further enhance

the drift performance.

Initial error can be nulled using a single 25 kΩ potentiometer

connected between V_OUT, Trim and GND. This is a coarse trim

with an adjustment range of 4% and is only included here for

compatibility purposes with other references. A fine trim can be

implemented by inserting a large value resistor (e.g. 1–5 MΩ) in

series with the wiper of the potentiometer. See Figure 2 above.

The trim range, expressed as a fraction of the output, is simply

greater than or equal to 2.1 kΩ/R_NULLfor either the 2.5 V or

3.0 V mode.

The external null resistor affects the overall temperature coeffi-

Figure 1. Schematic Diagram

For example a 1 mV (.03%) shift in the output caused by the

trim circuit, with a 100 ppm/°C null resistor will add less than

0.06 ppm/°C to the output drift (0.03% ϫ 200 ppm/°C, since

the resistors internal to the AD780 also have temperature coeffi-

cients of less than 100 ppm/°C).

The output voltage of the AD780 is determined by the configu-

ration of resistors R13, R14 and R15 in the amplifier’s feedback

loop. This sets the output to either 2.5 V or 3.0 V depending on

whether R15 (Pin 8) is grounded or not connected.

A unique feature of the AD780 is the low headroom design of

the high gain amplifier which produces a precision 3 V output

from an input voltage as low as 4.5 V (or 2.5 V from a 4.0 V

input). The amplifier design also allows the part to work with

V_IN= V_OUTwhen current is forced into the output terminal.

This allows the AD780 to work as a two terminal shunt regula-

tor providing a –2.5 V or –3.0 V reference voltage output with-

out external components.

The PTAT voltage is also used to provide the user with a ther-

mometer output voltage (at Pin 3) which increases at a rate of

approximately 2 mV/°C.

The AD780’s NC Pin 7 is a 20 kΩ resistor to V+ which is used

solely for production test purposes. Users who are currently us-

ing the LT1019 self-heater pin (Pin 7) must take into account

the different load on the heater supply.

NOISE PERFORMANCE

NOISE COMPARISON

The impressive noise performance of the AD780 can be further

improved if desired by the addition of two capacitors: a load ca-

pacitor C1 between the output and ground, and a compensation

capacitor C2 between the TEMP pin and ground. Suitable val-

ues are shown in Figure 3.

The wideband noise performance of the AD780 can also be ex-

pressed in ppm. The typical performance with C1, C2 is

0.6 ppm and without external capacitors is 1.2 ppm.

This performance is respectively 7ϫ and 3ϫ lower than the

specified performance of the LT1019.

TEMPERATURE PERFORMANCE

Figure 3. Compensation and Load Capacitor Combinations

The AD780 provides superior performance over temperature by

means of a combination of patented circuit design techniques,

precision thin film resistors and drift trimming. Temperature

performance is specified in terms of ppm/°C, but because of

nonlinearity in the temperature characteristic, the Box-Test

method is used to test and specify the part. The nonlinearity

takes the form of the characteristic S-shaped curve shown in

Figure 7. The Box-Test method forms a rectangular box around

this curve, enclosing the maximum and minimum output volt-

ages over the specified temperature range. The specified drift is

equal to the slope of the diagonal of this box.

C1 and C2 also improve the settling performance of the AD780

when subjected to load transients. The improvement in noise

performance is shown in Figures 4, 5 and 6 following.

TEMPERATURE OUTPUT PIN

TEMPERATURE TRANSDUCER CIRCUIT

The AD780 provides a “TEMP” output (Pin 3) that varies

linearly with temperature. This output can be used to monitor

changes in system ambient temperature and to initiate calibration

of the system if desired. The voltage V_TEMPis 560 mV at 25°C,

and the temperature coefficient is approximately 2 mV/°C.

Figure 8 shows the typical V_TEMPcharacteristic curve over tem-

perature taken at the output of the op amp with a noninverting

gain of five.

The circuit shown in Figure 9 is a temperature transducer which

a amplifies the TEMP output voltage by a gain of a little over 5

to provide a wider full scale output range. The trimpot can be

used to adjust the output so it varies exactly by 10 mV/°C.

To minimize resistance changes with temperature, resistors with

low temperature coefficients, such as metal film resistors should

be used.

_OUT. Care must be taken to buffer the TEMP output with a

suitable op amp, e.g., an OP07, AD820 or AD711 (all of which

would result in less than a 100 µV change in V_OUT). The rela-

tionship between I_TEMPand V_OUTis as follows:

The AD780’s quiescent current will vary slightly over tempera-

ture and input supply range. The test limit is 1 mA over the in-

dustrial and 1.3 mA over the military temperature range.

Typical performance with input voltage and temperature varia-

tion is shown in Figure 10 following.

The choice of C1 and C2 was dictated primarily by the need for a

relatively flat response that rolled off early in the high frequency

noise at the output. But there is considerable margin in the

choice of these capacitors. For example, the user can actually

put a huge C2 on the TEMP pin with none on the output pin.

However, one must either put very little or a lot of capacitance at

the TEMP pin. Intermediate values of capacitance can sometimes

cause oscillation. In any case, the user should follow the recom-

mendation in Figure 3.

TURN-ON TIME

The time required for the output voltage to reach its final value

within a specified error band is defined as the turn-on settling

time. The two major factors that affect this are the active circuit

settling time and the time for the thermal gradients on the chip

to stabilize. Typical settling performance is shown in Figure 11

LINE REGULATION

The AD780 is also ideal for use with higher resolution convert-

ers such as the AD7710/AD7711/AD7712. (See Figure 16.)

While these parts are specified with a 2.5 V internal reference,

the AD780 in 3 V mode can be used to improve the absolute ac-

curacy, temperature stability and dynamic range. It is shown fol-

lowing with the two optional noise reduction capacitors.

Line regulation is a measure of the change in output voltage due

to a specified change in input voltage. It is intended to simulate

worst case unregulated supply conditions and is measured in

µV/V. Figure 14 shows typical performance with 4.0 V < V_IN

15.0 V.

PRECISION REFERENCE FOR HIGH RESOLUTION

+5 V DATA CONVERTERS

The AD780 is ideally suited to be the reference for most +5 V

high resolution ADCs. The AD780 is stable under any capaci-

tive load, it has superior dynamic load performance, and the

3.0 V output provides the converter with maximum dynamic

range without requiring an additional and expensive buffer am-

plifier. One of the many ADCs that the AD780 is suited for is

the AD7884, a 16-bit, high speed sampling ADC. (See Figure

15.) This part previously needed a precision 5.0 V reference, re-

sistor divider and buffer amplifier to do this function.

+4.5 V REFERENCE FROM +5 V SUPPLY

Some +5 V high resolution ADCs can accommodate reference

voltages up to +4.5 V. The AD780 can be used to provide a

precision +4.5 V reference voltage from a +5 V supply using the

circuit shown following in Figure 17. This circuit will provide a

regulated +4.5 V output from a supply voltage as low as +4.7 V.

The high quality tantalum 10 µF capacitor in parallel with the

ceramic 0.1 µF capacitor and the 3.9 Ω resistor ensure a low

output impedance up to around 50 MHz.
