General description
The TDA8943SF is a single-channel audio power amplifier with an output power of
6 W at an 8
load and a 12 V supply. The circuit contains a Bridge Tied Load (BTL)
amplifier with an all-NPN output stage and standby/mute logic. The TDA8943SF
comes in a 9-lead single in-line (SIL) medium power package. The TDA8943SF 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.
