BA6780 / BA6780FP-Y are 2-channel driver ICs for CD changers that include a reversible, variable speed electronic governor and a reversible driver. They can be operated from just the negative supply to reduce influence on the positive power supply. The input uses PWM control and it is possible to directly input from a microprocessor running off the positive power supply. Applications include changers for CD players and MD players.
The BA6780 and BA6780FP-Y are integrated circuits designed as 2-channel drivers specifically for CD changers. These devices include a reversible, variable speed electronic governor and a reversible driver to control disc movement. A key feature is their ability to operate from just the negative supply voltage on sets with dual-rail power supplies, which reduces influence on the positive power supply. The input utilizes PWM control, allowing direct connection from a microprocessor running off the positive power supply.
