AK5572EN数据手册集成电路（IC）的ADC/DAC-特殊用途规格书PDF

描述 Description

The AK5572EN 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 AK5572EN 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 AK5572EN 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 2-to-1 mode.
