LM1876 is a dual 20W audio power amplifier with mute and standby modes. This article mainly introduce its pinout, application, datasheet and other detailed information about Texas Instruments LM1876.
LM1876T
The LM1876 is a stereo audio amplifier that can provide a typical continuous average output power of 20W per channel of 23W per channel with a THD+N lower than 0.1% to a 4Ω or 8Ω load. Each amplifier has an independent smooth transition fade-in/fade-out mute and an energy-saving standby mode that can be controlled by external logic. The performance of the LM1876 utilizes its self-peak instantaneous temperature (°Ke) (SPiKe™) protection circuit, which puts it in a class above discrete and hybrid amplifiers by providing inherent, application-dynamic-protected safe operating area (SOA). SPiKe protection means that these components are protected at the output to prevent overvoltage, undervoltage, and overload, including thermal runaway and instantaneous temperature peaks.
