Panasonic AN8819NFB Datasheet

ICs for CD/CD-ROM Player
■ Overview
The AN8819NFB is a 4ch. driver employing the low consumption power type H-bridge method which can operate with low voltage. It is suitable particularly for a portable CD player.
■ Features
Wide output D-range is available regardless of the ref-
erence voltage on the system
Driver input/output gain setting enabled by an external
resistance
•
For 2 channels, independent power on/off feature built­in. For other 2 channels, simultaneous on/off feature provided.
•
Thermal shut down circuit (with hysteresis) built-in
PWM control of the driver supply enabled by an exter­nal circuit for low consumption power operation
Construction of DC-DC converter enabled by an exter­nal circuit
•
Construction of ripple filter for D/A converter enabled
by an external capacitor
Construction of PWM control circuit of laser output by
an external circuit for low consumption power operation
Reset circuit with a mute and battery voltage detection circuit built-in for rational design of a set
■ Application
Actuator for CD, motor drive
