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 V
CC
/ 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 prod-
ucts up to 23MHz (A
V
= +25V/V to +101V/V). High-volt-
age 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/
MAX4274); and single/dual fixed gain plus internal
V
CC
/ 2 bias at the noninverting input (MAX4175/
MAX4275), which simplifies input biasing in single-supply
designs. 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 1k
load
while maintaining excellent DC accuracy. The amplifier
is stable for capacitive loads up to 470pF.
