TS4871D Datasheet PDF - ST Microelectronics

●DESCRIPTION

●The TS4871 is an Audio Power Amplifier capable of delivering 1W of continuous RMS Ouput Power into 8Ω load @ 5V.

●This Audio Amplifier is exhibiting 0.1% distortion level (THD) from a 5V supply for a Pout = 250mW RMS. An external standby mode control reduces the supply current to less than 10nA. An internal thermal shutdown protection is also provided.

●The TS4871 has been designed for high quality audio applications such as mobile phones and to minimize the number of external components.

●The unity-gain stable amplifier can be configured by external gain setting resistors.
