LM3875 Key Features

  • 23 56W Continuous Average Output Power Into 8Ω
  • 100W Instantaneous Peak Output Power Capability
  • Signal-to-Noise Ratio >95dB (min)
  • Output Protection From A Short to Ground or
  • Output Over-Voltage Protection Against Transients From Inductive Loads
  • Supply Under-Voltage Protection, Not Allowing Internal Biasing to Occur When |V+| + |V-| ≤ 12V, Thus Eliminating Turn-On
  • 11 Lead PFM Package
  • Wide Supply Voltage Range: |V+| + |V-| = 20V to 84V

LM3875 Description

The LM3875 is a high-performance audio power amplifier capable of delivering 56W of continuous average power to an 8Ω 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...
