AD8224ACPZ-R7

AD8224 is a single-supply, JFET input instrumentation amplifier. It requires the same board area as a typical single instrumentation amplifier yet doubles the channel density and offers a lower cost per channel without compromising performance. The device’s rail-to-rail output stage maximizes dynamic range on the low voltage supplies common in portable applications. It draws 750µA of quiescent current per amplifier, making it ideal for battery powered devices. In addition, the can 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. It is widely used in application such as medical instrumentation, precision data acquisition, transducer interfaces, differential drives for high resolution input ADCs, remote sensors etc.
