MAX4198：Micropower, Single-Supply, Rail-to-Rail 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 ±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 current to 6.5µA. 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-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.
