Overview
The AD627BRZ, produced by Analog Devices Inc., is a micropower, single- and dual-supply instrumentation amplifier. It is designed to deliver excellent ac and dc specifications while operating at a low maximum supply current of 85 μA. This amplifier offers superior flexibility, allowing users to set the gain with a single external resistor, and it conforms to the 8-lead industry-standard pinout configuration. The AD627BRZ is ideal for a wide range of applications, including battery-powered and industrial systems, due to its rail-to-rail output swing and low power consumption.
