AK5572
120dB 768kHz 32-bit 2ch  ADC with 4Filters
1. General Description
The AK5572 is a 32bit, 768kHz sampling, differential input A/D converter for digital audio systems. It
integrates an 2-channel A/D converter, suitable for mixers and automotive amplifier units. The AK5572 achieves
120dB dynamic range, 110dB S/(N+D) and 123dB dynamic range in Mono mode while keeping low power
consumption performance. Four types of digital filters are selectable according to the application. The AK5572
can be easily connected to a DSP by supporting TDM audio formats.
