General Description 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.
