General Description
The LM3875 is a high-performance audio power amplifier capable of delivering 56W of continuous average
power to an 8Ohm load with 0.1% THD+N from 20Hz to 20kHz.
The performance of the LM3875, 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, caused by shorts to the supplies,
thermal runaway, and instantaneous temperature peaks.
The LM3875 maintains an excellent signal-to-noise ratio of greater than 95dB(min) with a typical low noise
floor of 2.0V. It exhibits extremely low THD+N values of 0.06% at the rated output into the rated load over
the audio spectrum, and provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%.
Features
q
56W continuous average output power into 8Ohm
q
100W instantaneous peak output power capability
q
Signal-to-Noise Ratio >95dB (min)
q
Output protection from a short to ground or to the supplies via internal current limiting circuitry
q
Output over-voltage protection against transients from inductive loads
q
Supply under-voltage protection, not allowing internal biasing to occur when |V+| + |V-| < 12V, thus
eliminating turn-on and turn-off transients
q
11 lead TO-220 package
q
Wide supply voltage range: |V+| + |V-| = 20V to 84V
Applications
q
Component or compact stereos
q
Self-powered speakers
q
Surround-sound amplifiers
q
High-end stereo TVs
