[AK5522] AK5522 Differential Input Stereo 32-bit  ADC with Excellent PSRR 1.
General Description The AK5522 is a 32-bit, from 8kHz to 192kHz sampling A/D converter for line and microphone inputs of digital audio systems.
It achieves 108dB dynamic range and 98dB S/(N+D) while keeping low power consumption performance.
Four types of digital filters are integrated and selectable according to the sound quality preference.
The AK5522 has great power supply rejection ratio, (PSRR), and common mode rejection ratio, (CMRR), enabling to maintain sufficient characteristics when connecting USB bus power or DCDC converter output as a power supply.
It is suitable for applications with noisy power sup...
