Does anyone have a data sheet for a "Toshiba" IC Part No:TA7228P. There is no sign of it on the Toshiba Electronics web site and google just gets thousands of hits for merchants trying to sell parts. This is an old IC that I discovered in a box that I was clearing out, so its just curiosity on my part.
Thanks in advance for any info.
Regards
John.

My vrt databook just identifies it as a 5.7W audio amplifier.

Thanks John, Is the TA7222AP an equivalent part ?

Hi Franc, Thanks. I couldn't find any meaningful information on the net. I'm guessing that the device must be around 20 years old or so.
I think that thing was used in a lot of various CB radios, dual function, audio out on receive and used as a driver for the RF, if I'm not mistaken.
I mean it's just a power amp but was wired in so it was doing something in both transmit and receive functions.

AM CB radios have used a single audio amp since the '60s. The output trnsformer is used as the modulation transformer. The mic is connected, and the speaker disconnected when you transmit.
