Overview
The AD5338RBCPZ-RL7, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a low-power, dual, 10-bit buffered voltage output digital-to-analog converter (DAC). This device is designed for precision DC performance and low power consumption, making it suitable for a variety of applications requiring accurate and stable analog outputs.
The AD5338R operates from a single 2.7 V to 5.5 V supply and features a 2.5 V, 2 ppm/°C internal reference. It includes a gain select pin that allows for a full-scale output of either 2.5 V or 5 V. The device is available in both 3 mm × 3 mm LFCSP and 16-lead TSSOP packages.
