Class AB stereo headphone driver TDA1308; TDA1308A
FEATURES
• Wide temperature range
• No switch ON/OFF clicks
• Excellent power supply ripple rejection
• Low power consumption
• Short-circuit resistant
• High performance
GENERAL DESCRIPTION
TheTDA1308;TDA1308AisanintegratedclassABstereo
headphonedrivercontainedinanSO8,DIP8oraTSSOP8
plasticpackage. The device is fabricatedina 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.
– high signal-to-noise ratio
– high slew rate
– low distortion
• Large output voltage swing.
