Overview
The AD215AY, produced by Analog Devices Inc., is a high-speed input isolation amplifier designed to isolate and amplify wide bandwidth analog signals. This device ensures complete galvanic isolation between the input and output, including user-available front-end isolated power supplies. It is particularly useful in applications requiring high common-mode voltage (CMV) protection and fast analog signal measurement. The AD215AY operates over an extended industrial temperature range of –40°C to +85°C, making it suitable for various industrial environments.
