Digital to analog converter correction based on reading a channel of the digital to analog converter

A system, comprising:

• a digital-to-analog converter (DAC) having a plurality of channels;
• an analog-to-digital converter (ADC) communicatively coupled to the DAC, wherein the ADC is configured to read a channel of the plurality of channels;
• and
• a control circuit communicatively coupled to the DAC and the ADC, the control circuit configured to:
• receive an input from the ADC indicative of an output of the channel;
• calculate a compensation input to correct an error of the channel;
• output the compensation input to an input to the DAC;
• and
• correct the output of the plurality of channels based on the compensation input.
