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.  
2. Features  
Few external components  
Fixed gain  
Standby and mute mode  
No on/off switching plops  
Low standby current  
High supply voltage ripple rejection  
Outputs short-circuit protected to ground, supply and across the load  
Thermally protected
