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.
