Tool/software:
With a MICBIAS noise bandwith (20Hz-20kHz,A-weighted) of 1.6µV(rms) the TLV320ADCx140 can be used as a precise I²C-programmable voltage reference (6 different voltages), but what about accuracy?
In Datasheet(p.9) you don't find [Initial] accuracy [(max) (%) 25°C] or similar parameters.
Hi Michael,
Apologies for the delay.
Let me get back to you with this by tomorrow.
Thanks and Regards,

Hi Michael,
There is no specification for the accuracy of the MICBIAS voltage in the datasheet as you have mentioned. This voltage is meant to be used for biasing on-board microphones which will interface with the device. The variation at 25°C for a 2.75V MICBIAS can be in the range of +/-2.5%.
Thanks and Regards,
