Digitally controlled analog Input/Output stereo audio processor

[tolaemon]

I used the TDA7438D in an audio project some years ago, and I would like to use it again, but I've seen that most part of suppliers consider it as an obsolete IC.

For those who don't know: the TDA7438D ( and TDA7439 ) is a digitally controlled analog audio processor. So you can connect to this IC the analog signals to process and specify through the I2C the wished bass and treble levels. It was very practical and easy to use.

So I've been searching for a new option but I'havent been able to find anything similar. Can anybody give me the reference of an IC capable of controlling digitally an audio Analog Sterero signal? BGA options are not usefull to me because it is for a "home made" project

Thanks in advance!

Hey, I am planning on using that chip in my homemade amplifier. It's still available at Digikey. What experiences do you have with that chip? How is the sound?

what do you think about the TDA7318 and his companions?
there are some other chips like this on www.st.com
...
for the TDA7813, maybe you like this project

You could look at TDA7449, in fact I have a complete mini preamp based on that with a ATMega16, LCD and rotary encoder volume control.
