Headphone out with TA2024

maurycy · 29th January 2010, 01:08 PM

I have amp board with TA2024 that I would like to use as small speaker/headphone amplifier. I looked here for schematic but TA2024 is rated at 10W at 8Ohms and I am lost on what R1 and R3 values should I use (minimum they list is 20W).

I am also open to other suggestions on how to build headphone out from TA2024.

Thanks.

Warning: This unit is not designed to be used with bridged amplifiers! If there is a warning on your amp that states that the -ve speaker terminals must not be grounded, then you must not connect this adaptor, or the amplifier will be damaged.

And TA2024 is bridged.

TA2022 isn't, however.

I did more reading and see now that TA2024 is bridged and cannot be used :-(

Thanks for reply. I may check TA2022 then.
