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- and I2C-supported serial interface,

operating at clock rates of up to 50MHz (during

SPI writes to the device). 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.
