Overview
The AD204JY, produced by Analog Devices Inc., is a general-purpose, two-port, transformer-coupled isolation amplifier. This device is designed for applications where input signals must be measured, processed, and/or transmitted without a galvanic connection. The AD204JY offers a complete isolation function, providing both signal and power isolation in a single compact plastic SIP package. It is powered by an externally supplied clock and features an uncommitted op amp on the input stage, enhancing flexibility and ease of use.
