MAX4194-MAX4197 Precision Amplifiers

Analog Devices MAX4194-MAX4197 Micropower Precision Instrumentation Amplifiers use a three-op-amp topology that combines precision specifications and operation from a single +2.7V to +7.5V supply or dual ±1.35V to ±3.75V supplies. The supply current is just 93µA in normal operation and 8µA in shutdown mode with a 500ms enable time and 85µs 0.1% settling time (unity gain). Analog Devices MAX4194-MAX4197 Instrumentation Amplifiers preserve battery life in low-voltage battery-powered systems by pulsing the amplifier on/off at low-duty cycle. These modules feature excellent DC common-mode rejection (CMR) from 95dB to 115dB, depending on gain.
