LM3875
Overture Audio Power Amplifier Series
High-Performance 56W Audio Power Amplifier
General Description
The LM3875 is a high-performance audio power amplifier
capable of delivering 56W of continuous average power to
an 8
load with 0.1% (THD + N) from 20 Hz–20 kHz.
The performance of the LM3875, utilizing its Self Peak In-
stantaneous Temperature (Ke) (SPiKe) Protection Cir-
cuitry, puts it in a class above discrete and hybrid amplifiers
by providing an inherently, dynamically protected Safe Oper-
ating Area (SOA). SPiKe Protection means that these parts
are completely safeguarded at the output against overvolt-
age, undervoltage, overloads, including shorts to the sup-
plies, thermal runaway, and instantaneous temperature
peaks.
The LM3875 maintains an excellent Signal-to-Noise Ratio of
greater than 95 dB(min) with a typical low noise floor of
2.0 V. It exhibits extremely low (THD + N) values of 0.06%
at the rated output into the rated load over the audio spec-
trum, and provides excellent linearity with an IMD (SMPTE)
typical rating of 0.004%.
Features
n 56W continuous average output power into 8
n 100W instantaneous peak output power capability
n Signal-to-Noise Ratio >95 dB (min)
n Output protection from a short to ground or to the
supplies via internal current limiting circuitry
n Output over-voltage protection against transients from
inductive loads
n Supply under-voltage protection, not allowing internal
biasing to occur when |V
EE|+|VCC| ≤ 12V, thus
eliminating turn-on and turn-off transients
n 11 lead TO-220 package
Applications
n Component stereo
n Compact stereo
n Self-powered speakers
n Surround-sound amplifiers
n High-end stereo TVs
