3 Description

The 12-bit DAC60516 is a low-power, 16-channel,

buffered voltage-output digital-to-analog converter

(DAC). The DAC60516 includes a 2.5V, 15ppm/°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

DAC60516 operates from a single power supply.

Communication to the DAC60516 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

DAC60516 flexible interface enables operation with a

wide range of industry-standard microprocessors and

microcontrollers.

The DAC60516 is characterized for operation over the

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

in a small WQFN package.
