Datasheet
1. General description
The TDA1308 is an integrated class-AB stereo headphone driver contained in an SO8 or
a TSSOP8 plastic package. The device is fabricated in a 1 μm Complementary Metal
Oxide Semiconductor (CMOS) process and has been primarily developed for portable
digital audio applications.
