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 1kHz at 2 x 15W continuous average

output power into 4Ω or 8Ω:

0.1% (max)

THD+N at 1kHz at continuous average

Each amplifier has an independent smooth transition fade-

in/out mute and a power conserving standby mode which

can be controlled by external logic.

output power of 2 x 20W into 8Ω:

0.009% (typ)

4.2mA (typ)

Standby current:

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,

undervoltage, overloads, including thermal runaway and in-

stantaneous temperature peaks.

n SPiKe protection

n Minimal amount of external components necessary

n Quiet fade-in/out mute mode

n Standby-mode

n Isolated 15-lead TO-220 package

n Non-Isolated 15-lead TO-220 package

n Wide supply range 20V - 64V

Applications

n High-end stereo TVs
