Curious if anyone has a working solution for this:
I have a 16-bit PWM audio source coming from a display unit (unfilitered) and I want to plug it into the ADC input of the teensy using the AudioInputAnalog object of the Audio library. My source is a 3.3V PWM waveform coming from a 74LVC1G08 driver chip. There's a circuit example for converting PWM to Line Out as well as a circuit for Line In to ADC for the teensy, so I could obviously put the two together to achieve what I want. I'm just wondering if I can get away with less components, seems like some of them (10uF i.e.) will be redundant.
