3 Description

The DAC539E4W is 10-bit smart digital-to-analog

converters (DACs) with quad programmable

comparator inputs and quad general-purpose outputs.

A look-up table maps the comparator inputs to

the GPOs. The DAC539E4W also supports a

programmable delay to allow the input transitions to

settle. These devices provide NVM for storing the

configurations. This smart DAC functions without the

need for a processor (processor-less operation) using

LUT and NVM.

This device has an automatically detected SPI

and I2C interface and an internal reference. The

feature set combined with the tiny package and low

power make the smart DAC an excellent choice for

applications in fault management.
