Overview
The AD210JN, produced by Analog Devices Inc., is a precision, wide bandwidth 3-port isolation amplifier. It represents the latest generation of low-cost, high-performance isolation amplifiers. This device is manufactured using surface-mounted components in an automated assembly process, combining design expertise with state-of-the-art manufacturing technology. The AD210JN provides a complete isolation function with both signal and power isolation via internal transformer coupling, eliminating the need for an external DC/DC converter. It is powered by a single +15 V supply and maintains high performance under sustained common-mode stress, making it ideal for various applications requiring high accuracy and galvanic isolation.
