Class AB stereo headphone driver TDA1308

FEATURES

• Wide temperature range

• No switch ON/OFF clicks

• Excellent power supply ripple rejection

• Low power consumption

GENERAL DESCRIPTION

The TDA1308 is an integrated class AB stereo headphone
driver contained in an SO8 or a DIP8 plastic package. The
device is fabricated in a 1 mm CMOS process and has
been primarily developed for portable digital audio
applications.

• Short-circuit resistant

• High performance

– high signal-to-noise ratio
– high slew rate
– low distortion

• Large output voltage swing.
