1. General Description

The AK5552 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 AK5552 achieves

115dB dynamic range, 106dB S/(N+D) and 118dB dynamic range in Mono mode while keeping low power

consumption performance. Four types of digital filters are selectable according to the application. The AK5552

can be easily connected to a DSP by supporting TDM audio formats.
