[AK5574] 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. 2. Features  Sampling Rate: 8 kHz-768 kHz  Input: Full Differential Inputs  S/(N+D): 112 dB  DR: 121 dB (4-to-2 mode: 124 dB, 4-to-1 mode: 127 dB)  S/N: 121.
