Overview
The AD210BN, produced by Analog Devices Inc., is a precision, wide bandwidth 3-port isolation amplifier. It is part of a new 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 AD210BN provides complete isolation functions with both signal and power isolation via internal transformer coupling, eliminating the need for an external DC/DC converter. It operates on a single +15 V power supply and is designed to maintain high performance under sustained common-mode stress.
