LM3876T-LM3876TF
High-Performance 56W Audio Power Amplifier with Mute
LM3876 Overture™
Audio Power Amplifier Series
High-Performance 56W Audio Power Amplifier w/Mute
General Description

The LM3876isa high-performance audio power amplifier
capableof delivering 56Wof continuous average powerto8Ω load with 0.1% THD+N from 20Hz–20kHz.
The performanceof the LM3876, utilizingits Self PeakIn-
stantaneous Temperature (˚Ke) (SPiKe™) protection cir-
cuitry, putsitina class above discrete and hybrid amplifiers providingan inherently, dynamically protected Safe Op-
erating Area (SOA). SPiKe protection means that these
parts are completely safeguardedatthe output against ov-
ervoltage, undervoltage, overloads, including shortsto the
supplies, thermal runaway, and instantaneous temperature
peaks.
The LM3876 maintainsan excellent signal-to-noise ratioof
greater than 95dB (min) witha typical low noise floorof
2.0µV.It exhibits extremely low THD+N valuesof 0.06%at
the rated output intothe rated load overthe audio spectrum,
and provides excellent linearity withan IMD (SMPTE) typical
ratingof 0.004%.
Features
56W continuous average output power into8Ω 100W instantaneous peak output power capability Signal-to-Noise Ratio≥95 dB(min)An input mute function Output protection froma shortto groundortothe
suppliesvia internal current limiting circuitry Output over-voltage protection against transients from
inductive loads Supply under-voltage protection,not allowing internal
biasingto occur when |VEE|+|VCC|≤ 12V, thus
eliminating turn-on and turn-off transients 11-lead TO-220 package Wide supply range 20V- 94V
