DESCRIPTION

The TS419/TS421 is a monaural audio power am-

plifier driving in BTL mode a 16 or 32Ω earpiece 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 16Ω loads) 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.
