AK5538VN

111dB 768kHz / 32-bit 8 ch Advanced Audio ADC

Description

The AK5538VN is a 32-bit, 768kHz sampling, differential input A / D converter for digital audio systems. It achieves 111dB dynamic range and 103dB S / (N + D) while maintaining low power consumption performance. The AK5538VN integrates a 8 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 AK5538VN can be easily connected to a DSP by supporting TDM audio formats. Additionally, it supports DSD output up to 11.2MHz. The channel summation improves the dynamic range to 114dB in 8 to 4 mode, to 117dB in 8 to 2 mode and to 120dB in 8 to 1 mode.
