ADIAD8479BRZ
Overview
The AD8479BRZ is a precision difference amplifier designed to measure small differential voltages in the presence of very high common-mode voltages up to plus or minus 600V. It features a unique architecture that provides high CMRR and a rail-to-rail output while operating on a standard supply range of 2.5V to 18V. This makes it an ideal solution for high-side current sensing and battery stack monitoring where isolation-like performance is required without the complexity of an isolated amplifier.
Why Choose This Part
The device offers a superior common-mode voltage range of plus or minus 600V with a high 130 kHz bandwidth and an 8V/us slew rate for fast transient response. Its low supply current of 550uA and rail-to-rail output simplify power management in dense industrial sensor nodes.

Key Specifications
Getting Started
To evaluate this part, designers typically use the AD8479R-EBZ evaluation board which provides BNC connectors and easy access to pins. Ensure proper PCB creepage and clearance distances are maintained when working with the high-voltage inputs to satisfy safety standards.
