AD621 Instrumentation Amplifier

Analog Devices' instrumentation amps with 10 and 100 fixed gains

Image of Analog Devices’ AD621 Instrumentation amplifier ADI’s AD621 is an instrumentation amplifier that is low power and low noise with high accuracy. This amp has two fixed gain points, one at 10 at 800 kHz and the other at 100 at 200 kHz bandwidth. There are a variety of temperature options from -40°C to +85°C and -55°C to +125°C and they come in 8-pin, SOIC, DIP, and CERDIP packages. The AD621 is ideal for handheld, portable, and battery applications.
