DESCRIPTION
At 3.3v, the TS4973 is an Audio Power Amplifier capable of delivering 400mW of continuous RMS ouput power into a 8Ω bridged-tied loads with 1% THD+N, and 30mW( typ ) per channel of continuous average power into stereo 32Ω BTL loads with 0.5% THD+N from 20Hz to 20kHz. An external standby mode control reduces the supply current to less than 10nA. An internal over-temperature shutdown protection is provided.
