2.4.2 DC Analog Output

The analog output circuitry for this two-channel combined voltage and current output driver is realized with a dual output digital-to-analog converter (DAC) and two industrial analog voltage and current output drivers. The integrated output driver allows for digital selection between voltage V_OUT or current I_OUT modes on a combined output pin, reducing the connector and wiring costs. Digital isolation for the serial peripheral interface (SPI) and general purpose input and output (GPIO) control signals is accomplished using two four-channel digital isolators.

The TIDA-00454 board implements two analog outputs. The voltage and current of any phase can be transmitted as analog outputs.

The firmware is configured to send phase voltage on analog output 0 and the respective phase current on analog output 1.

The user can select a specific phase for analog output based on jumper settings mentioned in Section 3.1.1.1.
