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.
