Precision Differential Amplifiers
The MAX4198/MAX4199 low-power, rail-to-rail differential
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
В±1.35V to В±3.75V supplies, they consume only 42ВµA
while achieving -3dB bandwidths of 175kHz (MAX4198)
and 45kHz (MAX4199). These amplifiers feature a shutdown mode that reduces the supply current to 6.5ВµA.
The MAX4198/MAX4199 can drive 5kΩ loads to within
100mV from each rail. The standard differential amplifier 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-Railsв„ў.
The MAX4198/MAX4199 are offered in a space-saving
8-pin µMAX package. For complete micropower, rail-torail instrumentation amplifiers, see the MAX4194–
MAX4197 data sheet. Features
