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.
