2.5.3 DAC Interface

The DAC128S085CIMT part is used to generate the four channel analog outputs. The DAC128S085CIMT IC interfaces to the controlSOM through a SPI.

The ISO7741DBQR part is used to provide the electric isolation between SOM MCU and XDS110 emulator section.

Features of the DAC128S085CIMT:

  • INL: ±8 LSB maximum at 12-bit resolution
  • Dual reference voltages with range of 0.5V to VA
  • Power supply: 2.7V to 5.5V
  • 40MHz, SPI-compatible serial interface
