AD8224BCPZ-WP

AD8224BCPZ-WP is a precision, dual-channel, JFET input, rail-to-rail 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. This device’s rail-to-rail output stage maximizes dynamic range on the low voltage supplies common in portable applications. Its ability to run on a single 5V supply eliminates the need for higher voltage, dual supplies. It draws 750µA of quiescent current per amplifier, making it ideal for battery-powered devices. It is used in applications such as medical instrumentation, precision data acquisition, transducer interfaces, differential drives for high-resolution input ADCs, and remote sensors.
