Overview
The AD3542RBCPZ16-RL7, produced by Analog Devices Inc., is a low drift, dual channel, ultra-fast digital-to-analog converter (DAC) with 12-/16-bit accuracy. This voltage output DAC is designed for high-speed and high-precision applications, featuring multiple voltage span ranges and advanced interface options. It operates with a fixed 2.5 V internal voltage reference and incorporates three drift compensating feedback resistors for the internal transimpedance amplifier (TIA), ensuring stable and accurate output voltages.
