2 / 16 page  2002 Jul 19 2 Philips Semiconductors 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. SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
