CD players
BA6892FP
The BA6892FP is a 4-channel H-bridge BTL driver for CD players. Independent power supplies for each predriver and
power driver assure efficient operation at low voltages. Each channel is independently mutable.
F
Applications
CD players, CD-ROM drives and other optical disc devices

Features
1) 4-channel BTL driver in a HSOP 28-pin package,
ideal for application miniaturization.
2) Wide dynamic range.
3) Driver gain is adjustable with an attached resistor.
4) Independent power supply for each preamplifier and
power amplifier, for drives that operate efficiently on
low voltages.
5) Power amplifier current drops to an extremely low
level when the preamplifier power supply is lowered,
allowing for a standby mode.
