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.
