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