Stupid question: why did espressif leave out the DAC for the S3? I thought it was the new "default" base esp32. I know they had issues with the analog converter

Stupid question: why did espressif leave out the DAC for the S3? I thought it was the new "default" base esp32. I know they had issues with the analog converters in general but this is surprising to me!
- iamflimflam1 3y agoThe rumour is that the DAC took up a lot of die space and there wasn’t enough room. For most use cases PWM or PDM is sufficient. For more complex cases you are probably looking for some very specific performance characteristics and an external IC probably makes more sense.
- Nihilartikel 3y agoI'd love to have a dac built in, but it strikes me as being a bit like the old tv-vcr combos. If the built in vcr stinks or doesn't quite meet expectations you're either stuck with its subpar performance, or with the sunk cost of an unused or unusable feature. Many people might want an audio quality dac.. but 8 bit? 16? 24? Or maybe 4 bit is fine but you need 12 of them... Best to just have good peripheral support.
