Other Parts Discussed in Thread: BUF634,
Hi TI staff,
I would like to ask related question based on a thread "PCM512 + OPA1622 + BUF634" started by user..
My question refers to a schematic provided by TI staff member during the discussion.
Question is, why there is a need for an additional resistor R2 at the OPA1622 noninverting input right after the R1 resistor. Also what is the role of the components set at the output of BUF634BUF634 (R4+C2, Lt and Ct). How do the effect the sound?
Regards,
