GENERAL DESCRIPTION
The TDA1308; TDA1308A is an integrated class AB stereo
headphone driver contained in an SO8, DIP8 or a TSSOP8
plastic package. The device is fabricated in a 1 mm CMOS
process and has been primarily developed for portable
digital audio applications.
The difference between the TDA1308 and the TDA1308A
is that the TDA1308A can be used at low supply voltages.
