TPA6166A2: How to connect MOUTP/MOUTN to standard single end mic input?

Hi, Matsuda,

Welcome to E2E and thank you for your interest in our products!

Unfortunately, this device is a Class-G output device and the outputs cannot be directly connected in single-ended configuration. You would need to convert the output with an intermediary device such the THS3215. 

Or, in case you are not interested in add this devices, I would suggest to replace this device by a Class-AB device or another amplifier with single-ended output supported.

I hope this helps you. Please let me know i you have additional questions or comments.

Hi Luis-san,

Thank you for quick feedback.

Is it possible to connect only MOUTN to Audio codec with sigle-ended mic input??

MOUTP seems to come from Mic Bias in TPA6166 as per Simplified Schematic in datasheet.

So does only MOUTN swing ??

Hi Luis-san,

Thank you for your answer.

・When MICVDD is off, VDD is on , tpa6166a2 is set in shutdown mode, how much power is consumed from VDD ?

Hi, Matsuda,

During shutdown mode, VDD typically consumes 108uA if accessory is inserted. When there's no accessory inserted, the current consumption may be reduced down to 11uA.
