Overview
The AD3552RBCPZ16, produced by Analog Devices Inc., is a low drift, dual channel, ultra-fast, 16-bit accuracy, current output digital-to-analog converter (DAC). This device is highly configurable and can be set up in multiple voltage span ranges. It operates with a fixed 2.5 V reference and incorporates three drift compensating feedback resistors for the required external transimpedance amplifier (TIA) that scales the output voltage. The DAC supports both fast mode for maximum speed and precision mode for maximum accuracy, making it versatile for various high-performance applications.
