Systems and methods for providing an analog output signal using a class-d amplifier

A programmable controller, comprising:

• a processing system configured to generate a digital first internal signal at least partially according to (a) programming instructions provided to the processing system and (b) a digital first feedback signal;
• a first Class-D amplifier configured to amplify the digital first internal signal to generate a digital first output signal;
• a first filter configured to filter the digital first output signal to generate an analog first output signal;
• first sensing circuitry configured to sense the analog first output signal to generate an analog first feedback signal;
• and
• a first analog-to-digital converter (ADC) configured to convert the analog first feedback signal to the digital first feedback signal.
