Hello
My customer intends to use the PGA gain via ' on hte Fly' for portable audio( pro-sound).
However, if he had changed the gain 6dB( ex. 6db to 12db) at once, there are some click noise.
( If he changed 0.5dB, click is small)
Customer tested Follwing ( soft stepping ), but it was not effective to solve click.
> P0R19[D1-D0] : Left-ADC PGA Soft-Stepping Control
> P0R22[D1-D0] : Right-ADC PGA Soft-Stepping Control
Q1 In general, do you think PGA gain can be changed on the fly without click noise?
Q2 If there were any solutions ( register settings), please adivce.
I am sorry that such basic questions, but please adivice.
Best Regards
