AD620 Low Power Instrumentation Amplifier IC – SOIC-8 SMD Package

The AD620 is a low-cost, high-accuracy instrumentation amplifier designed for precision data acquisition systems. It requires only one external resistor to set gains of 1 to 10,000, making it easy to use. With its low power consumption and high performance, the AD620 is ideal for applications in medical instrumentation, weigh scales, and transducer interfaces. The IC is available in a compact SMD package, suitable for space-constrained designs.
