Description
The TS419 / TS421, is a monaural audio power amplifier driving in BTL mode a 16 or 32 Ω earpiece or receiver speaker. The main advantage of this configuration is to get rid of bulky output
capacitors.
Capable of descending to low
voltages, it delivers up to 220 mW per channel (into 16 Ω loads) of continuous average power with 0.2% THD+N in the audio bandwidth from a 5 V power supply.
An externally controlled standby mode reduces the supply current to 10 nA (typ.). The TS419 / TS421 can be configured by external gain-setting resistors.
