LM3875 3D Model
From 20Hz to 20kHz, the LM3875 is a high-performance audio power amplifier capable of producing 56 W of continuous average power to an 8Ω load with 0.1 per cent (THD + N). The LM3875 's performance, when combined with its Self Peak Instantaneous Temperature Protection Circuitry, elevates it above discrete and hybrid amplifiers by providing a dynamically protected Safe Operating Area (SOA). SPiKe Protection indicates that these parts are totally protected at the output from overvoltage, Undervoltage, overloads, including supply shorts, thermal runaway, and sudden temperature spikes.
6W continuous average output power into 8 Ω
100W instantaneous peak output power capability
Signal-to-Noise Ratio >95 dB (min)
Output protection from a short to ground or to the supplies via internal current limiting circuitry
Output over-voltage protection against transients from inductive loads
