4Ch. Linear Driver IC + DC-DC Converter Control for CD
s 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.
s 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 built-
in. 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 exter-
nal circuit for low consumption power operation
• Construction of DC-DC converter enabled by an exter-
nal 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
