LM2876 Datasheet High-performance 40w Audio Power Amplifier

Manufacturer: Texas Instruments

Overview: LM2876 www.ti.com SNAS088C – AUGUST 1995 – REVISED MARCH 2013 LM2876 Overture™ Audio Power Amplifier Series High-Performance 40W Audio Power Amplifier w/Mute Check for Samples:.

General Description

The LM2876 is a high-performance audio power amplifier capable of delivering 40W of continuous average power to an 8Ω load with 0.1% THD+N from 20Hz–20kHz.

The performance of the LM2876, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection circuitry, puts 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 completely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks.

Key Features

  • 1.
  • 23 40W Continuous Average Output Power Into 8Ω.
  • 75W Instantaneous Peak Output Power Capability.
  • Signal-to-Noise Ratio ≥ 95 dB(min).
  • An Input Mute Function.
  • Output Protection From A Short to Ground Or to the Supplies Via Internal Current Limiting Circuitry.
  • Output Over-Voltage Protection Against Transients From Inductive Loads.
  • Supply Under-Voltage Protection, Not Allowing Internal Biasing to Occur When |VEE| + |VCC| ≤ 12V, Thus Eli.
