■ Overview
The AN8730SB is a 4-channel driver IC, which can operate in a low voltage, employing the low power consumption type H-bridge system with a switching regulator. It is especially suited for a portable CD/MD player.

■ Features
• Low power consumption due to PWM control of power supply
• Wide output D-range independent of the reference voltage of the system
• Enable to set input/output gain by an external resistor
• Independent power on/off for 2 channels and simultaneous on/off for other 2 channels as well
• Battery voltage detection circuit built-in
• Thermal shut-down circuit (with hysteresis) built-in

■ Applications
• Portable CD/MD
