LM1876 Overture Audio Power Amplifier Series

Dual 20W Audio Power Amplifier with Mute and Standby

Modes

General Description

Key Specifications

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).

THD+N at 1 kHz at 2 x 15W continuous average

output power into 4Ω or 8Ω:

THD+N at 1 kHz at continuous average

output power of 2 x 20W into 8Ω:

Standby current:

0.1% (max)

Each amplifier has an independent smooth transition fade-in/

out mute and a power conserving standby mode which can

be controlled by external logic.

0.009% (typ)

4.2 mA (typ)

The performance of the LM1876, utilizing its Self Peak In-

™

stantaneous Temperature (˚Ke) (SPiKe ) Protection Cir-

Features

cuitry, places it in a class above discrete and hybrid amplifi-

ers by providing an inherently, dynamically protected Safe

Operating Area (SOA). SPiKe Protection means that these

parts are safeguarded at the output against overvoltage, un-

dervoltage, overloads, including thermal runaway and in-

stantaneous temperature peaks.
