1.5 W mono Bridge Tied Load (BTL) audio amplifier
Rev. 02 — 7 April 2000
Product specification
1. General description
The TDA8941P is a single-channel audio power amplifier with an output power of
1.5 W at an 16 load and a 9 V supply. The circuit contains a Bridge Tied Load
(BTL) amplifier with an all-NPN output stage and standby/mute logic. The TDA8941P
comes in a 8-pin dual in-line (DIP8) package. The TDA8941P 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.
