BA6796FP
The BA6796FP, an IC designed for CD and MD players, has a 5-channel BTL power driver and a standard operational
amplifier. The spindle and tray driver share a single output buffer, and are specified with a control pin. In addition, the
internal level shift circuit reduces the number of attached components.
