OPERATION

 

DACS demonstrates serial and parallel digital to analogue output conversion.

 

The serial chip, U3, is operated via the SPI output of the PIC MCU. When the simulation is run, the serial output voltage can be stepped up and down via the push buttons. The serial DAC provides a high resolution 16-bit output.

 

When the run button is then pressed, an 8-bit incrementing is output at Port D to the parallel DAC, U2, which causes a low resolution digital ramp waveform to be generated. This may be viewed on the virtual scope.
