5-channel driver for CD/DVD players
BA5815FM
Description The BA5815FM is a power driver IC for 5-channel CD and DVD players. Two channels incorporate filters and can connect PWM input directly. The additional 2 channels incorporate a standard operational amplifier. It can reduce the external components greatly. In the loading driver, output voltage can be adjusted to each device. Features 1) 4-channel BTL driver and 1-channel reversible driver 2) 2 channels are PWM input direct-coupled type. (Built-in primary filter) 3) 2 channels have standard operational amplifiers. 4) The device can be miniaturized due to the adoption of HSOP-M28 power package. 5) Built-in thermal shut down circuit 6) Wide dynamic range(9.2V(Typ.) at Vcc=12V, RL=8) HSOP-M28 Dimension (Units : mm)
