AD8222ACPZ-R7

AD8222 is a dual-channel, high performance instrumentation amplifier that requires only one external resistor per amplifier to set gains of 1 to 10,000. The device can also be configured as a single-channel, differential output instrumentation amplifier. Differential outputs provide high noise immunity, which can be useful when the output signal must travel through a noisy environment, such as with remote sensors. The configuration can also be used to drive differential input analogue-to-digital converters (ADCs). It is widely used in application such as multichannel data acquisition for ECG and medical instrumentation, industrial process controls, wheatstone bridge sensors, differential drives for high resolution input ADCs, remote sensors etc.
