Features

  • The higher performance replacement to the AK4376A that has been adopted by many smartphones

VELVET SOUND technology, used in AKM’s premium D/A converters for high-end audio products, has been further optimized for smartphones. The distortion characteristics of the high output power is improved compared with the AK4376A. The AK4377A achieves –106 dB THD+N at 25 mW output power. The AK4377A can reproduce the full original sound source, even while playing at loud volumes.

  • Audio characteristics are maintained even with a small circuit board

The AK4377A adopts an architecture which suppresses deterioration characteristics caused by external parts and the board layout. Therefore, it can provide stable and high-performance audio even on a highly integrated board such as one built for smartphones.
