AN8730SB
4-channel driver IC for optical disk
s Overview
The AN8730SB is a 4-channel driver IC, which can
operate in a low voltage, employing the low power con-
sumption type H-bridge system with a switching regula-
tor. It is especially suited for a portable CD/MD player.
s Features
• Low power consumption due to PWM control of power
supply
• Wide output D-range independent of the reference volt-
age of the system
• Enable to set input/output gain by an external resistor
• Independent power on/off for 2 channels and simulta-
neous on/off for other 2 channels as well
• Battery voltage detection circuit built-in
• Thermal shut-down circuit (with hysteresis) built-in
s Applications
• Portable CD/MD
