TS4871IST

TS4871IST is an audio power amplifier capable of delivering 1W of continuous RMS output power into 8 ohm load at 5V. This audio amplifier exhibits 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. It 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. It is used in applications such as mobile phones (cellular / cordless), laptop / notebook computers, PDAs, portable audio devices.
