LM1876TF/NOPB General Description

The LM1876 is a stereo audio amplifier capable of delivering typically 20W per channel of continuous average output power into a 4Ω or 8Ω load with less than 0.1% THD+N.

Each amplifier has an independent smooth transition fade-in/out mute and a power conserving standby mode which can be controlled by external logic.

The performance of the LM1876, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry, places it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe protection means that these parts are safeguarded at the output against overvoltage, undervoltage, overloads, including thermal runaway and instantaneous temperature peaks.

I**c 06/29/2023

I received my order earlier than expected and in optimal conditions

C**n 05/11/2023

Shipping very fast and the product is as it looks

C**s 02/03/2022

The goods came as described. Delivery more than a month. Everything is ok. I did not check in the work. Thank you seller!

P**a 12/03/2021

From this lot has not yet used-i use previously purchased. Excellent circuit board: small current consumption (for this it is necessary to solder the led), small size and configuration of the operation mode. Arrived in 30 days from the moment of order.
