AK5574

4-Channel Differential 32-bit ∆Σ ADC

1. General Description

The AK557x series is a 32-bit, 768 kHz sampling, differential input A/D converter for digital audio

systems. It achieves 121 dB dynamic range and 112 dB S/(N+D) while maintaining low power

consumption performance.

The AK5574 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

AK5574 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 124 dB in

4-to-2 mode and to 127 dB in 4-to-1 mode.
