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.
