SOT23, Rail-to-Rail, Fixed-Gain, Gain Amps/Open-Loop Op Amps
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 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 prod-
ucts up to 23MHz (AV= +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
VCC/ 2bias 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 1kΩload
while maintaining excellent DC accuracy. The amplifier
is stable for capacitive loads up to 470pF.

Note 1:MAX4174/MAX4175/MAX4281 and MAX4274/MAX4275/MAX4282 and MAX4284 are 100% production tested at = +25°C. All temperature limits are guaranteed by design.
Note 2:Guaranteed by design.
Note 3:The input common-mode range for IN_+ is guaranteed by a functional test. A similar test is done on the IN_- input. See the
Applications Informationsection for more information on the input voltage range of the GainAmp.
Note 4:For AV= -0.5V/V and AV= -0.25V/V, the output voltage swing is limited by the input voltage range.
Note 5:Includes noise from on-chip resistors.
Note 6:The gain accuracy test is performed with the GainAmp in noninverting configuration. The output voltage swing is limited by
the input voltage range for certain gains and supply voltage conditions. For situations where theoutput voltage swing is lim-
ited by the valid input range, the output limits are adjusted accordingly.
