Overview
The AD620ARZ-REEL, produced by Analog Devices Inc., is a low-cost, high-accuracy instrumentation amplifier. It is designed to offer high performance with minimal external components, requiring only one external resistor to set gains from 1 to 10,000. This amplifier is available in 8-lead SOIC packaging, making it suitable for compact and battery-powered applications. The AD620 is known for its low power consumption, with a maximum supply current of 1.3 mA, and its excellent DC and AC specifications, including low noise and high common-mode rejection ratio.
