TDA8944/TDA8944J pdf datasheet

1. General descripTIon

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

2 &TImes; 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.
