MAX4076

19-1526; Rev 1; 10/99 MAX4074–MAX4078† Micropower, SOT23, Rail-to-Rail, Fixed-Gain, GainAmp/Open-Loop Op Amps 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). Two versions are available in this amplifier family. The MAX4076/MAX4077/MAX4078 are single/dual/quad open-loop, unity-gain-stable op amps, and the MAX4074/M...
