TDA8944J

2 x 7 W stereo Bridge Tied Load (BTL) audio ampliﬁer

Rev. 02 — 14 February 2000

Product speciﬁcation

1. General description

The TDA8944J is a dual-channel audio power ampliﬁer with an output power of

2 × 7 W at an 8 Ω load and a 12 V supply. The circuit contains two Bridge Tied Load

(BTL) ampliﬁers with an all-NPN output stage and standby/mute logic. The TDA8944J

comes in a 17-pin DIL-bent-SIL (DBS) power package. The TDA8944J is

printed-circuit board (PCB) compatible with all other types in the TDA894x family.

One PCB footprint accommodates both the mono and the stereo products.

2. Features

■ Few external components

■ Fixed gain

■ Standby and mute mode

■ No on/off switching plops

■ Low standby current

■ High supply voltage ripple rejection

■ Outputs short-circuit protected to ground, supply and across the load

■ Thermally protected

■ Printed-circuit board compatible.

3. Applications

■ Mains fed applications (e.g. TV sound)

■ PC audio

■ Portable audio.
