The LM1876 is a stereo audio amplifier from Texas Instruments that delivers 20W of continuous average output power into a 4Ω or 8Ω load with THD+N less than 0.1%. It supports independent smooth transition fade-in/out mute and a power conserving standby mode that can be controlled by external logic. The standby current is 4.2mA.
The LM1876 is a stereo audio power amplifier capable of delivering typically 20 W per channel into 4 Ω or 8 Ω loads while maintaining less than 0.1 % THD+N. It includes SPiKe (Self‑Peak Instantaneous Temperature) protection that safeguards the device against over‑voltage, under‑voltage, overloads and thermal spikes.
The document provides key specifications, electrical characteristics, application circuits, mechanical dimensions and safety policy information, along with test circuit diagrams for both DC and AC performance verification.
