Texas Instruments DAC539E4W 10-Bit Smart DACs

Texas Instruments DAC539E4W 10-Bit Smart Digital-to-Analog Converters (DACs) come 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.

The Texas Instruments DAC539E4W has an automatically detected SPI and I²C interface and an internal reference. The feature set, combined with the low power and tiny package, makes the smart DAC an excellent choice for applications in fault management.
