Power Driver For CD-ROM

BA5912BFP

Features

: • Driver exclusively for the 2-ch BTL

• Use of an HSOP25PIN power package can achieve downsizing of the set.

• A wide dynamic range

• Using an external mute terminal, the output current can be muted.

(CH1, CH2 independently muted.)

• Muting both 2CHs will lead to the standby mode.

• Three power supply systems provided.(PreVcc, CH1 PowVcc, CH2 PowVcc)

• Two built-in general OP-AMPs installed.

• A built-in thermal shutdown circuit installed.
