DFN10 3X3 mm pitch 0.5 Pin Connections (top view) TS4974IQ DFN Package Description At 3.3v, the TS4974 is a dual power audio amplifier capable of delivering 380mW of www.DataSheet4U.com continuous RMS ouput power into a 8Ω bridgedtied loads with 1% THD+N. An external standby mode control reduces the supply current to less than 2µA. An internal over-temperature shutdown protection is provided. The TS4974 has been designed for high quality audio applications such as mobile phones and for minimizing the number of external components. The TS4974 features a 16 step digital volume control through two discrete control Up and Down pins. The start-up gain is internally fixed to -12dB. An integrated debounce system prevents voltage pikes on UP/DOWN pins during volume control mode to be taken into account during a debounce time of 10ms (typ.).
