TDA7566

[Raj23]

We are working on one of our project which previously using TDA7566 IC.

Can anyone suggest any pin-to-pin compatible IC for TDA7566?

Are the following IC's are compatible - TDA7580, TDA7388, TDA7850?

I would like to know more about the 3 pins (pin number: 22, 25, 4) of TDA7566 as there are mainly 3 pins which are not match with TDA7384A & TDA7385 and similar case with other IC's.

Welcome @Raj23, to the community!

As you may have seen, the TDA7566 has been discontinued for a long time. Pins 22, 25 and 4 in question provided functions that are unfortunately no longer included in any other class AB amp still available: I2C Clock/Data and CD_Out (Clip Detector Output). These pins are used by all the alternatives as MUTE, DIAGNOSTICS and ST-BY.

I'm sorry, but apart from remaining stocks of the TDA7566, which you may find somewhere on the Internet, I can't give you a pin2pin compatible alternative if your project uses the pins mentioned.
