TDA8942P
2 x 1.5 W stereo Bridge Tied Load (BTL) audio amplifier
Rev. 02 — 14 March 2000
Product specification
1. General description
The TDA8942P is a dual-channel audio power amplifier for an output power of
2 × 1.5 W at a 16 load and a 9 V supply. 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.
