LM3886 Datasheet High-performance 68w Audio Power Amplifier

Manufacturer: Texas Instruments

Overview: LM3886 .ti. SNAS091C – MAY 1999 – REVISED MARCH 2013 LM3886 Overture™ Audio Power Amplifier Series High-Performance 68W Audio Power Amplifier w/Mute Check for Samples:.

General Description

The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4Ω load and 38W into 8Ω with 0.1% THD+N from 20Hz–20kHz.

The performance of the LM3886, 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 pletely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks.
