The AD620AN is a cost-effective, highly precise instrumentation amplifier requiring just one external resistor to adjust gains from 1 to 10,000. Its compact 8-lead SOIC and DIP packaging offers lower power consumption, making it ideal for portable or battery-operated devices. It suits precision data acquisition systems like weigh scales and transducer interfaces with exceptional accuracy, low offset voltage and drift. Its low noise and input bias current make it suitable for medical applications such as ECG and blood pressure monitors. Powered by Superβeta processing, it ensures minimal input bias current. With its low input voltage noise and fast settling time, it functions efficiently as a preamplifier and is well-suited for multiplexed applications. Moreover, its affordability allows for designs with one amplifier per channel, making it a versatile choice across various applications.
