More details

The AD202MW is a general-purpose, dual-port, transformer-coupled isolation amplifier for a wide range of applications where input signals must be measured, processed and/or transmitted without current connections. This industry standard isolation amplifier offers complete isolation, both signal isolation and power isolation, in a compact plastic-sealed SIP or DIP single package. The device is directly powered by a +15 V DC power supply. The AD202MW utilizes internal transformer coupling to provide overall current isolation between the input and output stages of the isolation amplifier. The AD202MW is fully functional and requires no external DC-DC converter from the user. As a result, designers can minimize the necessary circuit overhead, thereby reducing overall design and device costs.

The AD202MW is designed to provide flexibility and ease of use, including non-dedicated operational amplifiers at the input level. It offers a bipolar ±5 V output range, adjustable gain range from 1 to 100 V/V, maximum nonlinearity (K-level) of +0.025%, and common mode rejection (CMR) of 130 dB.
