Product Overview

The LM4667MM/NOPB is a fully integrated single-supply high efficiency Switching Audio Amplifier. It features an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. Eliminating the output filter reduces parts count, simplifies circuit design and reduces board area. The LM4667 processes analog inputs with a delta-sigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators. Operating on a single 3V supply, it is capable of driving 8R transducer loads at a continuous average output of 450mW with less than 1%THD+N. Its flexible power supply requirements allow operation from 2.7 to 5.5V. The LM4667 has high efficiency with a 8R transducer load compared to a typical class AB amplifier. With a 3V supply, the IC's efficiency for a 100mW power level is 74%, reaching 84% at 450mW output power.
  • No output filter required for inductive transducers
  • Minimum external components
  • Click and pop suppression circuitry
  • Micro-power shutdown mode
  • Short-circuit protection
  • 5ms (typical) Very fast turn on time
  • 7kV ESD susceptibility
  • Green product and no Sb/Br
