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.
