Overview
The AD5316RBCPZ-RL7, produced by Analog Devices Inc., is a member of the nanoDAC® family. It is a low power, quad, 10-bit buffered voltage output Digital-to-Analog Converter (DAC). This device features a 2.5 V, 2 ppm/°C internal reference and a gain select pin, allowing for full-scale output of either 2.5 V or 5 V. The AD5316R operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design, ensuring high precision and reliability.
