The MAX4074–MAX4078 GainAmp™ op amp family
combines low-cost Rail-to-Rail
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 (A
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 GainAmp 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 applications, the MAX4074/MAX4076
are available in space-saving SOT23-5 packages.
