TDA8941P

TDA8941P 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 Ω 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. 2.
