AN8814SB
4-channel driver IC for optical disk drive
■ Overview
The AN8814SB is a BTL system 4-channel
driver and is encapsulated in the SMD package
which excels in heat radiation characteristic.
■ Features
• Wide output dynamic range regardless of refer-
ence voltage of the system
• Driver I/O gain setting is possible with an addi-
tional external resistor
• 3.3 V supply voltage is available due to an exter-
nal PNP-tr.
• Additional OP-amp. built-in
■ Applications
• MD, CD/CD-ROM drive
• DVD/DVD-ROM drive
