Description

The AK5574EN is a 32-bit, 768kHz sampling, differential input A / D converter for digital audio systems. It achieves 121dB dynamic range and 112dB S / (N + D) while maintaining low power consumption performance. The AK5574EN integrates a 4 channel A / D converter, suitable for mixers and multi-channel recorders. Four types of digital filters are integrated and selectable according to the sound quality preference.  The AK5574EN can be easily connected to a DSP by supporting TDM audio formats. Additionally, it supports DSD output up to 11.2MHz. The channel summation mode improves the dynamic range performance by summing-up multiple channel A / D data and averaging. The dynamic range is improved to 124dB in 4 to 2 mode and to 127dB in 4 to 1 mode.

Key Features

  • Fully differential input
  • Dynamic range S / N = 121dB (4 to 2 mode | 124dB, 4 to 1 mode | 127dB)
  • Equipped with 4 types of LPF and digital HPF

Applications

  •                                 Studio mixer and other equipment that handles high resolution and DSD sound source recording. etc.
