●General description

●The TDA8944J is a dual-channel audio power amplifier with an output power of 2×7 W at an 8Ωload 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.
