DESCRIPTION
This audio power amplifier is capable of delivering 1.2 W of continuous RMS output power into an 8 load at 5 V. An externally controlled standby mode reduces the supply current to less than 10 nA. The unity-gain stable amplifier can be configured by external gain setting resistors. January 2019 This is information on a product in full production.
