Question on DA chip

Assyst1606 · 20th January 2009, 02:18 PM

Hi all,
I have an old Pioneer LD player model CLD-D580, which uses a DA chip PD2026B (28 pins). I do not have the player's schematic & the chip's data sheet.
But i would like to find out which are the Vout pins for the L & R on the DA chip.
May i know usually where are the Vout pins go to (which component)?
Thanks!

Hi guytou,
Thanks for the info.
I think PD2026A is close to PD2026B (i hope). I got info for PD2028B but it's different from my PD2026B.
