General Description

The MAX4174/MAX4175/MAX4274/MAX4275 Gain Amp™ family combines a low-cost Rail-to-Rail®op amp with precision internal gain-setting resistors and VCC/ 2 biasing. 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 only 300µA.

GainAmp amplifiers are optimally compensated for each gain version, achieving exceptional GBW products up to 23MHz (AV= +25V/V to +101V/V). High-voltage fault protection withstands ±17V at either input without excessive current draw.
