Product Name :

Silicon Monolithic Integrated Circuit

BTL Driver For CD-ROM

Device Name : BA5983FM

Features

: • Driver exclusively for the 4-ch BTL

• HSOP-M28 PIN power package

• A wide dynamic range [PreVcc=8V, PowVcc=5V, 4V(Typ.) when RL=8Ω]

• A built-in thermal shutdown circuit installed.

• The power supplies such as PreVcc, PowVcc of CH1 and CH2, and PowVcc of

CH3 and CH4 are supplied independently to achieve an efficient drive.

• The standby mode can be controlled independently in CH1 to 3 and CH4.

• Setting all of CH1-4 to the standby mode leads the entire circuit to the standby

mode.

• The driver pre-stage OP-amp features GND-sense and output rail-to-rail to

make this IC suitable for a low voltage DSP.
