Product specification
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
– high signal-to-noise ratio
– high slew rate
– low distortion
• Large output voltage swing.
GENERAL DESCRIPTION
The TDA1308; TDA1308A is an integrated class AB stereo
headphone driver contained in an SO8, DIP8 or a TSSOP8
plastic package. The device is fabricated in a 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.
QUICK REFERENCE DATA
VDD =5V; VSS =0V; Tamb =25 °C; fi = 1 kHz; RL =32 Ω; unless otherwise specified.
Notes
1. VDD = 5 V; VO(p-p) = 3.5 V (at 0 dB).
2. VDD = 2.4 V; VO(p-p) = 1.62 V (at −4.8 dBV); for TDA1308A only.
3. VDD = 2.4 V; VO(p-p) = 1.19 V (at −7.96 dBV); for TDA1308A only.
