These ICs are part of a portable CD, Cass, Radio PANASONIC MODEL RX-DT680.
Yesterday I spent more than an hour trying to get the specs sheets from different sources, like Parts Miner etc.
I went on the ROHM site for the BA392O, found nothing I went on the SANYO site for the LA4108, found nothing.
Can anyone refer me to site that gives the specs, and where I wont spend hours trying to get them. Thanks Réjean SERVICE ELECTRONIQUE SATELLITE QUÉBEC
