Stereo source selector IC

speakerguy79 · 19th November 2008, 06:16 PM

Hi,

I am looking for a stereo source selector IC (analog switch). My old HT receiver uses an LC7822 for this function but it is discontinued. I would like at least 3 or 4 stereo source inputs and one stereo output. Control interface will be via microcontroller so control interface is no worry - can be serial data control or just pin configurable.

Thanks for any help!

Does it have to be an IC ?

Which I designed as part of this,
My MOSFET amplifier designed for music.

I would prefer an IC solution for simplicity and cost, this will be a commercial application (and I wouldn't want to steal your work for my design).

That's nice

There used to be TDAxxxx (I think ) chip that was a complete preamp, input selection etc all controlled by an I2C bus. Had tone controls as well, but that's going back a good few years.
May be someone else can remember the number.

How about NJR # NJM2750?
