TS4974 1W Differential Audio Power Amplifier

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 .

TS4974 1W Differential Audio Power Amplifier with Up/Down Digital Volume Control Pins PRODUCT PREVIEW s s s s s s s s s s s Operating from VCC = 2.5V to 5.5V Zero pop&clickless circuit 1.W output power @ Vcc=5V, THD=1%, F=1kHz, with 8Ω Load Ultra low consumption in standby mode (2µA max.) 85dB PSRR @ 217Hz 16 digital volume control steps Two up and down volume control discrete pins Gain range from -33dB to + 12dB Integrated debouncing system Ultra fast start up time: 15ms typ. DFN10 3X3 mm pit.

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.). TS4974IQ -
