Does ESP32S3 have two 8 bit DACs?

[djixon]

There is no mention about DAC(s) in the latest TRM for ESP32S3 except in a table where IO_MUX registers are counted IO_MUX_GPIO17_REG and IO_MUX_GPIO18_REG. However, there is no function for DAC(s) in IO_MUX table pin functions. So obviously it is an error. How should I know what to populate into bitfield IO_MUX_MCU_SEL of those registers, when there is no function mentioned in the table. Is there any example of such a trivial thing as writing an 8 bit value in DAC_REG and getting corresponding analog voltage at some output pad?

Not sure if that's actually an error. Might just be some misunderstanding about what DAC should mean in that context or some relation to the I2S.

I doubt it: https://esp32.com/viewtopic.php?t=22740#p82152
But you can use PWM or the I2S's PDM...

It looks that two 8 bits DACs are removed from ESP32S3 .... anyway, I will redesign part of my circuit to use PWM instead, however info that DA converters are not presented anymore should be placed in documentation

If by "removed" you mean there never were "8 bit DACs" in the S3 and no-one ever claimed there would be, then yes, they were "removed".

If only there was some sort of "product selector" page on the internet where people could select the features they need and it would tell them which chips are available with this set of features before they decide what to build their design on...
