General Description

The MAX4074–MAX4078 GainAmp? op amp family combines low-cost Rail-to-Rail? op amps with precision internal gain-setting resistors. Factory-trimmed on-chip resistors decrease design size, cost, and layout, and provide 0.1 gain accuracy. Fixed inverting gains from -0.25V/V to -100V/V or noninverting gains from +1.25V/V to +101V/V are available. These devices operate from a single +2.5V to +5.5V supply and consume just 34μA. GainAmp amplifiers are optimally compensated for each gain version, achieving gain bandwidth (GBW) products up to 4MHz (AV = +25V/V to +101V/V). High-voltage fault protection withstands ±17V at either input without damage or excessive current draw (MAX4074/MAX4075 only).
