[AK5552] AK5552 2-Channel Differential 32-bit  ADC 1. General Description The AK555x series is a 32-bit, 768 kHz sampling, differential input A/D converter for digital audio systems. It achieves 115 dB dynamic range and 106 dB S/(N+D) while maintaining low power consumption performance. The AK5552 integrates a 2-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 AK5552 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 118 dB in 2-to-1 mode. 2.
