Class AB stereo headphone driver
TDA1308
FEATURES
·
Wide temperature range
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.
·
No switch ON/OFF clicks
·
Excellent power supply ripple rejection
·
Low power consumption
·
Short-circuit resistant
·
High performance
– high signal-to-noise ratio
– high slew rate
– low distortion
·
Large output voltage swing.
