A current sensor with PWM output is a very useful type of device. Traditionally, the device can serve in a digital application where the host microcontroller can determine the ratio of the on-time to the off-time of the sensor output signal. …

it takes in audio on ADC0 and uses a dual pwm to create 16b audio out. you can process the audio in-between and make a low-fi effects pedal. it can be used for just analog out as well, and is much higher quality than using analogwrite (although more complicated too). there is a much more in-depth tutorial on pwm in general up here:

microcontrollers offer a Pulse-Width Modulation (PWM) module, which can be combined with a low-pass filter to create an analog output. This technical brief highlights the use of a low-pass filter to transform a PWM signal into an analog signal. © 2020 Microchip Technology Inc. Technical Brief DS90003250A-page 1
