TLV320AIC3204 ESD/RESET

Q: TLV320AIC3204 ESD/RESET

Have you seen false RESET issues on TLV320AIC3204 when Analog and Digital grounds bounce due to ESD events? 

Unrelated to ESD testing,  Register 68/ Page 0 resets to 0x6F, datasheet states this should RESET to 0x0F; please comment.

 

A: Re: TLV320AIC3204 ESD/RESET Questions

Digital I/O signals are referenced to DVSS. If /RESET line goes low, or DVDD supply is removed, then it is possible that it might reset the part. Best way to know is to measure between IOVDD and DVSS and between /RESET and DVSS (with proper precautions).

Regarding p0_r68, yes, it should be 0x6F.
