LTC2630  
Single 12-/10-/8-Bit Rail-to-  
Rail DACs with Integrated  
Reference in SC70  
FEATURES  
DESCRIPTION  
The LTC®2630 is a family of 12-, 10-, and 8-bit voltage-  
output DACs with an integrated, high-accuracy, low-drift  
reference in a 6-lead SC70 package. It has a rail-to-rail  
output buffer and is guaranteed monotonic.  
Integrated Precision Reference  
2.5V Full Scale 10ppm/°C (LTC2630-L)  
4.096V Full Scale 10ppm/°C (LTC2630-H)  
Maximum INL Error: 1 LSB (LTC2630A-12)  
Low Noise: 0.7mV , 0.1Hz to 200kHz  
P-P  
The LTC2630-L has a full-scale output of 2.5V, and  
operates from a single 2.7V to 5.5V supply. The  
LTC2630-Hhasafull-scaleoutputof4.096V, andoperates  
from a 4.5V to 5.5V supply. Each DAC can also operate in  
supplyasreferencemode, whichsetsthefull-scaleoutput  
to the supply voltage.  
Guaranteed Monotonic over Temperature  
Selectable Internal Reference or Supply as Reference  
2.7V to 5.5V Supply Range (LTC2630-L)  
Low Power Operation: 180μA at 3V  
Power Down to 1.8μA Maximum (C and I Grades)  
Power-on Reset to Zero or Midscale Options  
SPI Serial Interface  
The parts use a simple SPI/MICROWIRE™ compatible  
3-wire serial interface which operates at clock rates up  
to 50MHz.  
Double-Buffered Data Latches  
Tiny 6-Lead SC70 Package  
The LTC2630 incorporates a power-on reset circuit. Op-  
tions are available for reset to zero or reset to midscale  
after power-up.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may affect device  
reliability and lifetime.  
Note 4: This IC includes current limiting that is intended to protect the  
device during momentary overload conditions. Junction temperature can  
exceed the rated maximum during current limiting. Continuous operation  
above the specified maximum operating junction temperature may impair  
device reliability.

OPERATION  
The LTC2630 is a family of single voltage output DACs in  
6-lead SC70 packages. Each DAC can operate rail-to-rail  
referenced to the input supply, or with its full-scale volt-  
age set by an integrated reference. Twelve combinations  
of accuracy (12-, 10-, and 8-bit), power-on reset value  
(zero or midscale), and full-scale voltage (2.5V or 4.096V)  
are available. The LTC2630 is controlled using a 3-wire  
SPI/MICROWIRE compatible interface.  
Transfer Function

Table 1. Command Codes  
Command*  
For some applications, downstream circuits are active  
during DAC power-up, and may be sensitive to nonzero  
outputs from the DAC during this time. The LTC2630  
contains circuitry to reduce the power-on glitch: the  
analog output typically rises less than 5mV above zero  
scale during power on if the power supply is ramped  
to 5V in 1ms or more. In general, the glitch amplitude  
decreases as the power supply ramp time is increased.  
See “Power-On Reset Glitch” in the Typical Performance  
Characteristics section.

While the minimum input sequence is 24 bits, it may  
optionally be extended to 32 bits to accommodate micro-  
processors that have a minimum word width of 16 bits  
(2bytes).Tousethe32-bitwidth,8don’t-carebitsaretrans-  
ferred to the device first, followed by the 24-bit sequence  
described. Figure 3b shows the 32-bit sequence.  
TheCS/LDinputisleveltriggered. Whenthisinputistaken  
low, it acts as a chip-select signal, enabling the SDI and  
SCK buffers and the input shift register. Data (SDI input)  
is transferred at the next 24 rising SCK edges. The 4-bit  
command, C3-C0, is loaded first; then 4 don’t-care bits;  
and finally the 16-bit data word. The data word comprises  
the 12-, 10- or 8-bit input code, ordered MSB-to-LSB, fol-  
lowed by 4, 6 or 8 don’t-care bits (LTC2630-12, -10 and  
-8 respectively; see Figure 2). Data can only be transferred  
to the device when the CS/LD signal is low, beginning on  
the first rising edge of SCK. SCK may be high or low at  
the falling edge of CS/LD. The rising edge of CS/LD ends  
the data transfer and causes the device to execute the  
command specified in the 24-bit input sequence. The  
complete sequence is shown in Figure 3a.  
The 16-bit data word is ignored for all commands that do  
not include a Write operation.  
Power-Down Mode  
For power-constrained applications, power-down mode  
can be used to reduce the supply current whenever the  
DACoutputisnotneeded.Wheninpower-down,thebuffer  
amplifier,biascircuit,andreferencecircuitaredisabledand  
draw essentially zero current. The DAC output is put into  
a high-impedance state, and the output pin is passively  
pulled to ground through a 200kΩ resistor. Input and DAC  
register contents are not disturbed during power-down.  
The command (C3-C0) assignments are shown in Table 1.  
The first three commands in the table consist of write and  
update operations. A Write operation loads a 16-bit data  
word from the 24-bit shift register into the input register.  
In an Update operation, the input register is copied to the  
DAC register and converted to an analog voltage at the  
DAC output. Write to and Update combines the first two  
commands. The Update operation also powers up the  
DAC if it had been in power-down mode. The data path  
and registers are shown in the Block Diagram.  
The DAC can be put into power-down mode by using  
command 0100. The supply current is reduced to 1.8μA  
maximum when the DAC is powered down.  
Normal operation resumes after executing any command  
that includes a DAC update, as shown in Table 1. The DAC  
is powered up and its voltage output is updated. Normal  
settling is delayed while the bias, reference, and amplifier  
circuits are re-enabled. The power up delay time is 18μs  
for settling to 12 bits.

ThePCboardshouldhaveseparateareasfortheanalogand  
digital sections of the circuit. A single, solid ground plane  
should be used, with analog and digital signals carefully  
routed over separate areas of the plane. This keeps digital  
signals away from sensitive analog signals and minimizes  
the interaction between digital ground currents and the  
analog section of the ground plane. The resistance from  
the LTC2630 GND pin to the ground plane should be as  
low as possible. Resistance here will add directly to the  
effective DC output impedance of the device (typically  
0.1Ω). Note that the LTC2630 is no more susceptible to  
this effect than any other parts of this type; on the con-  
trary, it allows layout-based performance improvements  
to shine rather than limiting attainable performance with  
excessive internal resistance.  
reference voltage and the supply current is reduced.  
Voltage Output  
TheLTC2630’sintegratedrail-to-railamplifierhasguaran-  
teed load regulation when sourcing or sinking up to 10mA  
at 5V, and 5mA at 3V.  
Load regulation is a measure of the amplifier’s ability to  
maintain the rated voltage accuracy over a wide range of  
load current. The measured change in output voltage per  
change in forced load current is expressed in LSB/mA.  
DC output impedance is equivalent to load regulation, and  
may be derived from it by simply calculating a change in  
units from LSB/mA to ohms. The amplifier’s DC output  
impedance is 0.1Ω when driving a load well away from  
the rails.  
Another technique for minimizing errors is to use a sepa-  
rate power ground return trace on another board layer.  
The trace should run between the point where the power  
supply is connected to the board and the DAC ground pin.  
Thus the DAC ground pin becomes the common point for  
analog ground, digital ground, and power ground. When  
the LTC2630 is sinking large currents, this current flows  
out the ground pin and directly to the power ground trace  
without affecting the analog ground plane voltage.  
When drawing a load current from either rail, the output  
voltage headroom with respect to that rail is limited by  
the 50Ω typical channel resistance of the output devices  
(e.g., when sinking 1mA, the minimum output voltage is  
50Ω • 1mA, or 50mV). See the graph “Headroom at Rails  
vs. Output Current” in the Typical Performance Charac-  
teristics section.  
The amplifier is stable driving capacitive loads of up to  
500pF.  
It is sometimes necessary to interrupt the ground plane  
to confine digital ground currents to the digital portion of  
the plane. When doing this, make the gap in the plane only  
as long as it needs to be to serve its purpose and ensure  
that no traces cross over the gap.  
Rail-to-Rail Output Considerations  
In any rail-to-rail voltage output device, the output is  
limited to voltages within the supply range.
