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.
