DESCRIPTION
The TS419/TS421 is a monaural audio power am-
plifier driving in BTL mode a 16 or 32
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 16
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.
APPLICATIONS
s 16/32 ohms earpiece or receiver speaker driver
s Mobile and cordless phones (analog / digital)
s PDAs & computers
s Portable appliances
ORDER CODE
