■ 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
