TS4871数据手册ST中文资料规格书

描述 Description

The TS4871 is an audio power amplifier capable of delivering 1 W of continuous RMS output power into 8 Ω load @ 5 V.

This audio amplifier exhibits 0.1% distortion level (THD) from a 5 V supply for a Pout = 250 mW RMS. An external standby mode control reduces the supply current to less than 10 nA. 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.
