Single/Dual/Quad, Low-Power, Single-Supply, Rail-to-Rail I/O Op Amps with Shutdown

Please check latest availability status for a specific part variant.


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-mode voltage range extends 250mV beyond VEE and VCC, 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 and other low-voltage, single-supply applications. 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 precision, low-voltage data-acquisition systems. The MAX4330 is available in the space-saving 5-pin SOT23 package, and the MAX4331/MAX4333 are offered in a µMAX® package.
