[AK5538]
AK5538
8-Channel Differential 32-bit ADC
1. General Description The AK553x series is a 32-bit, 768 kHz sampling, differential input A/D converter for digital audio systems. It achieves 111 dB dynamic range and 103 dB S/(N+D) while maintaining low power consumption performance. The AK5538 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 AK5538 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 114 dB in 8-to-4 mode, to 117 dB in 8-to-2 mode and to 120 dB in 8-to-1 mode.
