TDA1308; TDA1308A
Class-AB stereo headphone driver
Rev. 04 — 25 January 2007
Product data sheet
1. General description
The TDA1308; TDA1308A is an integrated class-AB stereo headphone driver contained in
an SO8, DIP8 or a TSSOP8 plastic package. The TDA1308AUK is available in an 8 bump
wafer level chip-size package (WLCSP8). The device is fabricated in a 1
µm
Complementary Metal Oxide Semiconductor (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.
