♦ 3MHz Gain-Bandwidth Product

The MAX4330–MAX4334 single/dual/quad op amps

combine a wide 3MHz bandwidth, low-power operation,

and excellent DC accuracy with Rail-to-Rail inputs and

outputs. These devices require only 245µA per amplifier,

and operate from either a single +2.3V to +6.5V supply

or dual ±1.15V to ±3.25V supplies. The input common-

♦ 245µA Quiescent Current per Amplifier

♦ Available in Space-Saving SOT23-5 Package

(MAX4330)

♦ +2.3V to +6.5V Single-Supply Operation

♦ Rail-to-Rail Input Common-Mode Voltage Range

♦ Rail-to-Rail Output Voltage Swing

♦ 250µV Offset Voltage

mode voltage range extends 250mV beyond V and

, and the outputs swing rail-to-rail. The MAX4331/

MAX4333 feature a shutdown mode in which the output

goes high impedance and the supply current decreases

to 9µA per amplifier.

Low-power operation combined with rail-to-rail input

common-mode range and output swing makes these

amplifiers ideal for portable/battery-powered equipment

a nd othe r low-volta g e , s ing le -s up p ly a p p lic a tions .

Although the minimum operating voltage is specified at

2.3V, these devices typically operate down to 2.0V. Low

offset voltage and high speed make these amplifiers

excellent choices for signal-conditioning stages in pre-

c is ion, low-volta g e d a ta -a c q uis ition s ys te ms . The

MAX4330 is available in the space-saving 5-pin SOT23

package, and the MAX4331/MAX4333 are offered in

a µMAX package.

♦ Low-Power, 9µA (per amp) Shutdown Mode

(MAX4331/MAX4333)

♦ No Phase Reversal for Overdriven Inputs

♦ Capable of Driving 2kΩ Loads

♦ Unity-Gain Stable

voltage, single-supply operation. The input stage con-

sists of se p a ra te NPN a nd PNP d iffe re ntia l sta ge s,

which operate together to provide a common-mode

range extending to 0.25V beyond both supply rails. The

crossover region, which occurs halfway between V

and V , is extended to minimize degradation in CMRR

caused by mismatched input pairs. The input offset volt-

age is typically 250µV. Low offset voltage, high band-

wid th, ra il-to-ra il c ommon-mod e inp ut ra ng e , a nd

rail-to-rail outputs make this family of op amps an excel-

lent choice for precision, low-voltage data-acquisition

systems.

R3 = R1 R2

Since the input stage consists of NPN and PNP pairs,

the input bias current changes polarity as the input volt-

age passes through the crossover region. Match the

effective impedance seen by each input to reduce the

offset error due to input bias currents flowing through

external source impedances (Figures 1a and 1b). The

c omb ina tion of hig h s ourc e imp e d a nc e with inp ut

capacitance (amplifier input capacitance plus stray

capacitance) creates a parasitic pole that produces an

underdamped signal response. Reducing input capaci-

tance or placing a small capacitor across the feedback

resistor improves response.

The MAX4330–MAX4334’s inputs are protected from

large differential input voltages by internal 1kΩ series

resistors and back-to-back triple diode stacks across

the inputs (Figure 2). For differential input voltages

(much less than 1.8V), input resistance is typically

2.3MΩ. For differential input voltages greater than 1.8V,

input resistance is around 2kΩ, and the input bias cur-

rent can be approximated by the following equation:

R3 = R1 R2

= (V

- 1.8V) / 2kΩ

In the re g ion whe re the d iffe re ntia l inp ut volta g e

approaches 1.8V, input resistance decreases exponen-

tially from 2.3MΩ to 2kΩ as the diode block begins con-

ducting. Inversely, the bias current increases with the

same curve.

Driving a capacitive load can cause instability in many

op amps, especially those with low quiescent current.

The MAX4330–MAX4334 are stable for capacitive loads

up to 150pF. The Capacitive Load Stability graph in the

Figures 4 and 5 show the response of the MAX4331

with an excessive capacitive load, compared with the

response when a series resistor is added between the

output and the capacitive load. The resistor improves

the circuit’s response by isolating the load capacitance

from the op amp’s output (Figure 6).

The MAX4330–MAX4334 output stage can drive up to a

2kΩ load and still typically swing within 125mV of the

rails. Figure 3 shows the output voltage swing of a

MAX4331 configured as a unity-gain buffer. The operat-

ing voltage is a single +3V supply, and the input volt-

age is 3Vp-p. The output swings to within 70mV of V

a nd 100mV of V , e ve n with the ma ximum loa d

S h u t d o w n Mo d e

The MAX4331/MAX4333 feature a low-power shutdown

mode. When the shutdown pin (SHDN) is pulled low, the

supply current drops to 9µA per amplifier (typical), the

amplifier is disabled, and the outputs enter a high-

impedance state. Pulling SHDN high or leaving it float-

ing enables the amplifier. Figures 10 and 11 show the

MAX4331/MAX4333’s output voltage and supply-current

responses to a shutdown pulse.

P o w e r-Up

The MAX4330–MAX4334 outputs typically settle within

5µs after power-up. Using the test circuit of Figure 7,

Figures 8 and 9 show the output voltage and supply

current on power-up and power-down.

Do not three-state SHDN. Due to the output leakage

currents of three-state devices and the small internal

pull-up current for SHDN, three-stating this pin could

result in indeterminate logic levels, and could adversely

affect op-amp operation.

SHDN

The logic threshold for SHDN is always referred to V

not GND. When using dual supplies, pull SHDN to V

to place the op amp in shutdown mode.

Good layout technique helps optimize performance by

decreasing the amount of stray capacitance at the op

amp’s inputs and outputs. To decrease stray capaci-

tance, minimize trace lengths by placing external com-

ponents close to the op amp’s pins.
