The Pi Code Zero’s Dialog Semiconductor DA7212 has a SNR of 90 dB ADC, 100 dB DAC https://www.mouser.co.uk/datasheet/2/698/REN_da7212_datasheet_3v4_DST_201805...
The DACBerry is slightly higher at 92dB ADC, 102dB DAC but the difference isn’t supposed to be perceivable by the human ear.

thanks very much, Julian
looks promising!
this link refers to a 'programmable microphone bias level' http://osaelectronics.com/get/raspberry/dacberry/400/m/datasheet/DACBerry_40... so could well work with electret microphones
i don t know how to interpret the SNR figures

Hi all,
Just a heads up that the DACBerry 400 M for Raspberry Pi 400 (the keyboard hybrid) has a line/mic input. I would assume its powered but there’s no mention of it on the datasheet: https://osaelectronics.com/get/raspberry/dacberry/400/m/datasheet/DACBerry_4...
It also has some integrated DSP
