General Description
The MAX4490/MAX4491/MAX4492 single/dual/quad, low-cost CMOS op amps feature Rail-to-Rail®input and
output capability from either a single +2.7V to +5.5V supply or dual ±1.35V to ±2.75V supplies. These ampli
fiers exhibit a high slew rate of 10V/µs and a gain-band width product of 10MHz. They can drive 2kΩresistive
loads to within 55mV of either supply rail and remain unity-gain stable with capacitive loads up to 300pF.
