4-channel H-bridge type BTL driver for

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.

FApplications

CD players, CD-ROM drives and other optical disc devices

FFeatures

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.

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
