... This amplifier is also offered in three fixed-gain versions: the MAX4195 (G = +1V/V), the MAX4196 (G = +10V/V), and the MAX4197 (G = +100V/V). The fixed-gain instrumentation amplifiers fea- ture a shutdown function that reduces the quiescent current to 8µA. A traditional three operational amplifier configuration is used to achieve maximum DC precision. The MAX4194– ...

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... Micropower, Single-Supply, Rail-to-Rail, Precision Instrumentation Amplifiers Detailed Description The MAX4194–MAX4197 family of low-power instru- mentation amplifiers implements a three-amplifier topol- ogy (Figure 1). The input stage is composed of two operational amplifiers that together provide a fixed-gain differential and a unity common-mode gain. The output stage is a conventional differential amplifier that pro- vides an overall common-mode rejection of 115dB (G = 25kΩ ...

... With an output load of 5kΩ tied to V put voltage swings within 100mV of the rails. Shutdown Mode The MAX4195–MAX4197 feature a low-power shutdown mode. When the shutdown pin (SHDN) is pulled low, the internal amplifiers are switched off and the supply current drops to 8µA typically (Figures 5a, 5b, and 5c). ...

... Capacitive-Load Stability The MAX4194–MAX4197 are stable for capacitive loads up to 300pF (Figure 6a). Applications that require greater capacitive-load driving capability can use an isolation resistor (Figure 6b) between the output and the capacitive load to reduce ringing on the output sig- nal ...

... For best performance, bypass each power supply to ground with a separate 0.1µF capacitor. Transducer Applications The MAX4194–MAX4197 instrumentation amplifiers can be used in various signal-conditioning circuits for ther- mocouples, PT100s, strain gauges (displacement sen- sors), piezoresistive transducers (PRTs), flow sensors, and bioelectrical applications ...
