19-1526; Rev 1; 10/99 Micropower, SOT23, Rail-to-Rail, Fixed-Gain, GainAmp/Open-Loop Op Amps General Description Features The MAX4074–MAX4078 GainAmp™ op amp family ¦ Internal Gain-Setting Resistors in SOT23 combines low-cost Rail-to-Rail® op amps with precision Packages (MAX4074) internal gain-setting resistors. Factory-trimmed on-chip ¦ 0.1% Gain Accuracy (RF/RG) (MAX4074/75) resistors decrease design size, cost, and layout, and provide 0.1% gain accuracy. Fixed inverting gains from ¦ 54 Standard Gains Available (MAX4074/75) -0.25V/V to -100V/V or noninverting gains from +1.25V/V ¦ Open-Loop, Unity-Gain-Stable Op Amps to +101V/V are available. These devices operate from a single +2.5V to +5.5V supply and consume just 34µA. (MAX4076/77/78) GainAmp amplifiers are optimal
