The MAX4198/MAX4199 low-power, Rail-to-Rail
ential amplifiers are ideal for single-supply applications
that benefit from a low 0.01% gain error. The MAX4198
is factory trimmed to a fixed gain of +1V/V, and the
MAX4199 is trimmed to a fixed gain of +10V/V. Capable
of operating from a single +2.7V to +7.5V supply or
from dual ±1.35V to ±3.75V supplies, they consume
only 42µA while achieving -3dB bandwidths of 175kHz
(MAX4198) and 45kHz (MAX4199). These amplifiers
feature a shutdown mode that reduces the supply cur-
rent to 6.5µA.
The MAX4198/MAX4199 can drive 5kΩ loads to within
100mV from each rail. The standard differential amplifi-
er configurations provide common-mode rejection of
90dB for the MAX4198 and 110dB for the MAX4199.
The input common-mode voltage range for the
MAX4198 extends 100mV Beyond-the-Rails™.
The MAX4198/MAX4199 are offered in a space-saving
8-pin µMAX package. For complete micropower, rail-to-
rail instrumentation amplifiers, see the MAX4194–
MAX4197 data sheet.
