TDA8945S
15 W mono Bridge Tied Load (BTL) audio amplifier
Rev. 02 — 7 April 2000
Product specification
1. General description
The TDA8945S is a single-channel audio power amplifier with an output power of
15 W at an 8
load and an 18 V supply. The circuit contains a Bridge Tied Load
(BTL) amplifier with an all-NPN output stage and standby/mute logic. The TDA8945S
comes in a 9-lead single in-line (SIL) power package. The TDA8945S 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.
