My question is, why is every integrated adc/dac in almost every commercial microcontroller stagnant at 12 bit resolution? It's been that way for decades now. Is 16 bit that difficult?
- Archit3ch 3y agoIIRC, switching EM noise from the microcontroller itself (at the MHz range) starts to affect the ADC/DAC. Your "16”-bit converter gives 12 useful bits and 4 bits of junk. For an ADC, you can get back useful bits via Oversampling & Decimation, at the expense of bandwidth.
