CLASS AB STEREO HEADPHONE
DRIVER
DESCRIPTION
ꢀ
The SC1308L is a Class AB stereo headphone driver chip
utilizing CMOS Technology specially designed for portable
digital audio applications. It is housed in an 8-pin DIP or SO
package and is functionally compatible with TDA1308. Pin
assignment and application circuits are optimized for lower
cost effectiveness and easy PCB Layout.
