Signal Frequency=1kHz; 24bit Data; Measurement Frequency=20Hz∼20kHz at 48kHz, 20Hz~40kHz at fs=96kHz,
10. PSR is applied to AVDD, DVDD and TVDD with 1kHz, 50mVpp. VREFH pin is held a constant voltage.
11. S/N measured by CCIR-ARM is 102dB(@fs=48kHz).
8. S/N measured by CCIR-ARM is 98dB(@fs=48kHz).
9. Input resistance is 16kΩ typically at fs=96kHz.
