产品概述

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/MAX4075 are single/dual fixed-gain op amps. The input common-mode voltage range of the open-loop amplifiers extends from 150mV below the negative supply to within 1.2V of the positive supply. The outputs can swing rail-to-rail and drive a 1kΩ load while maintaining excellent DC accuracy (MAX4074/MAX4075 only). The amplifiers are stable for capacitive loads up to 100pF.

For space-critical operations, the MAX4074/MAX4076 are available in space-saving SOT23-5 packages.
