DESCRIPTION  
The TS419/TS421 is a monaural audio power am-  
plifier driving in BTL mode a 16 or 32earpiece or  
receiver speaker. The main advantage of this con-  
figuration is to get rid of bulky ouput capacitors.  
Capable of descending to low voltages, it delivers  
up to 220mW per channel (into 16loads) of con-  
tinuous average power with 0.2% THD+N in the  
audio bandwidth from a 5V power supply.

An externally controlled standby mode reduces  
the supply current to 10nA (typ.). The TS419/  
TS421 can be configured by external gain-setting  
resistors or used in a fixed gain version.
