LM3886 OvertureAudio Power Amplifier Series
High-Performance 68W Audio Power Amplifier w/Mute
General Description
The LM3886 is a high-performance audio power amplifier
capable of delivering 68W of continuous average power to a
4load and 38W into 8with 0.1% (THD + N) from
20 Hz–20 kHz.
The performance of the LM3886, 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 LM3886 maintains an excellent Signal-to-Noise Ratio of
greater than 92 dB with a typical low noise floor of 2.0 µV. It
exhibits extremely low (THD + N) values of 0.03% at the
rated output into the rated load over the audio spectrum, and
provides excellent linearity with an IMD (SMPTE) typical rat-
ing of 0.004%.
Features
n 68W cont. avg. output power into 4at VCC = ±28V
n 38W cont. avg. output power into 8at VCC = ±28V
n 50W cont. avg. output power into 8at VCC = ±35V
n 135W instantaneous peak output power capability
n Signal-to-Noise Ratio 92 dB
n An input mute function
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 |VEE| + |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
