Download the LM4781TABD datasheet PDF. This datasheet also covers the LM4781 variant, as both devices belong to the same 3-channel 35w audio power amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

The LM4781 is a three channel audio amplifier capable of typically delivering 35W per channel of continuous average output power into an 8Ω load with less than 0.5% THD+N from 20Hz - 20kHz.

Features

  • 1.
  • 23 SPiKe Protection.
  • Low External Component Count.
  • Quiet Fade-In/Out Mute Mode.
  • Wide Supply Range: 20V - 70V.
  • Signal-to-Noise Ratio ≥ 93dB (ref. to PO = 1W).
