Hello
I am sorry to bother you, but please let me have questions again.
My customer had tested 6 pcs PCM1795 VcomR terminal voltage.
Average of 6 unit was 2.35V. ( 2.34V ~ 2.377V)
The schematic which customer had tested is as same as PCM1795 data sheet p37.
Q1
In your previous advice, Vcom_x voltage sould be fixed 2.50V regardless of Vcc , but 2.35 Volt is reasonable? How do you think?
( I think It may be reasonable, because there are no description in d/s, so minimum / maximum voltage of Vcom_x is unknown..)
Q2
Do you have distribution data of Vcom_L and Vcom_R ? ( This is customer's inquiry )
With My Best Regards
.
