5-channel driver for CD/DVD players
BA5815FM
Description
Dimension (Units : mm)
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.

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=8Ω)
