SNAS097C –MAY 1999–REVISED APRIL 2013

LM1876 Overture™ Audio Power Amplifier Series

Dual 20W Audio Power Amplifier with Mute and Standby Modes

Check for Samples: LM1876

FEATURES

DESCRIPTION

The LM1876 is a stereo audio amplifier capable of

•

SPiKe Protection

delivering typically 20W per channel of continuous

average output power into a 4Ω or 8Ω load with less

than 0.1% THD+N.

•

Minimal Amount of External Components

Necessary

•

Quiet Fade-In/Out Mute Mode

Standby-Mode

Each amplifier has an independent smooth transition

fade-in/out mute and a power conserving standby

mode which can be controlled by external logic.

Isolated 15-Lead TO-220 Package (PFM)

Non-Isolated 15-lead TO-220 Package

Wide Supply Range 20V - 64V

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.

APPLICATIONS

•

High-End Stereo TVs

Component Stereo

Compact Stereo

KEY SPECIFICATIONS

•

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

(max)

•

THD+N at 1kHz at continuous average output

power of 2 x 20W into 8Ω: 0.009% (typ)

Standby current: 4.2mA (typ)
