AK5552VN

115dB 768kHz / 32-bit 2-ch Premium ADC

Description

The AK5552VN is a 32-bit, 768kHz sampling, differential input A / D converter for digital audio systems. It achieves 115dB dynamic range and 106dB S / (N + D) while maintaining low power consumption performance.
The AK5552VN 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 AK5552VN 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 118dB in 2 to 1 mode.
