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.
Three versions are available in this amplifier family: single/ dual/quad open-loop, unity-gain stable (MAX4281/ MAX4282/MAX4284); single/dual fixed gain (MAX4174/...
