Overview
The AD3542R is a low drift, dual channel, ultra-fast, 12-/16-bit accuracy, voltage output digital-to-analog converter (DAC) designed by Analog Devices Inc. This device is configured to operate in multiple voltage span ranges and features a fixed 2.5 V internal voltage reference. It is particularly suited for applications requiring high speed and precision, such as instrumentation, hardware in the loop, process control equipment, medical devices, and automated test equipment.
