ROHM BA6791FP, BA6790FP Datasheet
Optical disc ICs
4-channel BTL driver for CD players
BA6790FP / BA6791FP
The BA6790FP and BA6791FP are 4-channel BTL drivers for CD player actuators and motors. These ICs have internal
5 V regulators and general purpose operational amplifiers, and are mounted to a 28-pin HSOP package, allowing for
the miniaturization of applications.
Applications
CD players and portable CD
Features
1) 4-channel BTL driver.
2) HSOP 28-pin package allows for miniaturization of
applications.
3) Wide dynamic range. (typically 5.4V when V
and RL = 8Ω)
CC = 8V
4) Internal thermal shutdown circuit.
5) Gain is adjustable with a single attached resistor.
6) Internal 5V regulator. (requires attached PNP transistor)
7) Internal general purpose operational amplifier.
