D Datasheet PDF ( Pinout ) – 2SD

2ssd1944 I would guess at least some of them are for output muting. I agree with cetoole. Also, the Pass D1 stage is another one to look at.

Post 5 of It would be pretty simple to dtasheet bias some so as to drop the input impedance further. Your username or email address: You should be able to easily trace the output RCA back to the opamp. What I did was to change out the opamp and replaced it with an OPA I performed a similar mod on a Sony DVD player. Here are some pics of the board.

Post 7 of After bypassing the electrolytics in the power supply and adding damping to the chassis I tackled the analog stage. Is there somewhere where we can buy PCBs of discrete analog stages? Post 1 of I will post some pictures of the board.

Post 12 of It would be much more worthwhile to replace the whole output stage, preferably with a discrete solution. Need help for transistors upgrade.

May 30, at Thanks for the help. Post 14 of Post 11 of By continuing to use this site, you are consenting to our use of cookies. For my DVD player, it wasn’t worth the money to rebuild the entire analog output stage. No, create an account now. You must log in or sign dattasheet to reply here.

May 9, at 3: Post 9 of Colin cetoole looked the design over and saw some things he didn’t like. There are improved variations on this, as it was really just posted to get people thinking, but this is probably the simplest it will get while still offering good performance. Share This Page Tweet.

What DAC is in here? Current or voltage output?

This isnt for the schematic I am currently working on, but should be pretty good.
