The LE58QL021 is a 4 channel CODEC used for telecommunications systems. I need to find a replacement for this, since it is going EOL.
What we need - 4 simultaneous channels of audio in & out.
We also use the GPIO pins on the LE58, so will need something to replace them as well.
Ideally, 1 IC for space and lower parts count / cost, but CODECS with 2 or 1 channel that can daisy chain off the microprocessor port would work also.
A future product we are looking at developing would have 8 CODEC channels.
I do not see any direct or a good similar alternative at this time. so for now you may need to ,
check these out QL 03 and others
From talking to the tech support at Microchip, the entire QLSLAC family is going EOL.
We are planning a last time buy for the part we use now.
I did not expect to find anything drop in.
We need to re design the circuit for a CODEC that is an active part, that isn’t going to EOL on us in a few years.
Dtief190, I didn’t find many chips similar in function to the LE58QL021 chip.
Click here for possible alternates.
Sorry we didn’t have any better options.
I found one that we will look into -
