Datasheet
General description
The TDA8942P is a dual-channel audio power amplifier for an output power of 2 x 1.5 W at a 16 Ohm load and a 9 V supply. The amplifier is even capable of delivering 2 x 3 W music power at an 8 Ohm load. The circuit contains two Bridge Tied Load (BTL) amplifiers with an all-NPN output stage and standby/mute logic. The TDA8942P comes in a 16-pin dual in-line (DIP) package.The TDA8942P 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.
