Product overview
Description
The TS419/TS421 is a monaural audio power amplifier driving in BTL mode a 16 or 32
Capable of descending to low voltages, it delivers up to 220mW per channel (into 16
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.
