MAX4174 - Fixed-Gain GainAmps/Open-Loop Op Amps

General Description

The MAX4174/MAX4175/MAX4274/MAX4275 GainAmp™ 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.

19-1407; Rev 3; 8/99 SOT23, Rail-to-Rail, Fixed-Gain GainAmps/Open-Loop Op Amps General Description The MAX4174/MAX4175/MAX4274/MAX4275 GainAmp™ 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.
