5. In case of 16bit, DR and S/N of ADC are 98dB. DR of DAC is 98dB.
6. S/N measured by CCIR-ARM is 96dB at each converter and 94dB at ADC to DAC loopback.
7. Full scale input for each AIN+/- pin is 1.5Vpp in differential mode.
8. PSR is applied to VA, VD with 1kHz, 50mVpp. VREFH pin is held a constant voltage.
9. As the input data is “0”, S/N is 100dB regardless of resolution.
