3 Description

The 16-bit DAC80516 is a low-power, 16-channel,

buffered voltage-output digital-to-analog converter

(DAC). The DAC80516 includes a 2.5V, 5ppm/°C

internal reference, eliminating the need for an

external precision reference in most applications. A

user selectable gain configuration can be used to

provide full-scale output voltages of 2.5V or 5V. The

DAC80516 operates from a single power supply.

Communication to the DAC80516 is performed

through an SPI-supported serial interface and

operates at clock rates of up to 50MHz. The VIO

pin enables serial interface operation from 1.7V

to 5.5V. The DAC80516 flexible interface enables

operation with a wide range of industry-standard

microprocessors and microcontrollers.

The DAC80516 is characterized for operation over the

temperature range of –40°C to +125°C and available

in a small WQFN package.
