Does anyone have information on how it works and the datasheet, and if there is an alternative IC?
Hello bani_98,
Welcome to the DigiKey TechForum.
We do not carry this IC, and we do not have a datasheet for it.
I searched on the internet and was unable to find a datasheet, so I am unable to look for a possible alternate.
This IC SN61112B5 is used in a JBL SRX835P amplifier designed by Crown audio, but I couldn’t find the Service Manual either.
