5-channel driver for CD/DVD players

BA5815FM

Description Dimension (Units : mm)

The BA5815FM is a power driver IC for 5-channelCD and DVD players. Two channels incorporatefilters and can connect PWM input directly.The additional 2 channels incorporate a standardoperational amplifier. It can reduce the externalcomponents greatly. In the loading driver, outputvoltage can be adjusted to each device.

00W098A

HSOP-M28

November, 2000

Features

1) 4-channel BTL driver and 1-channel reversible driver2) 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 circuit6) Wide dynamic range(9.2V(Typ.) atVcc=12V, RL=8)
