6.1 Overview

The DAC80516 is a low-power, sixteen-channel, buffered voltage-output digital-to-analog converter (DAC) with 16-bit resolution. The DAC80516 includes a 2.5V internal reference and provides user-selectable gain configuration through software, which can be used to set the full-scale output voltage range for groups of four DACs at a time (see also Section 6.3.1.1). The device operates from a single 2.7V to 5.5V supply. Communication to the DAC80516 is performed through a serial interface that supports SPI and I2C communication.

The DAC80516 incorporates a power-on-reset circuit that powers up and maintains the DAC outputs at zero scale until a valid code is written to the device.

A clear pin enables a simultaneous update of multiple DAC channels to specified clear values.
