(Ta= -40 ∼ +105°C; AVDD1=AVDD2=3.0∼ 3.6V, DVDD=1.6∼ 2.0V, TVDD1=TVDD2=1.6∼ 3.6V; DEM=OFF)
Note 13. The passband and stopband frequencies scale with fs (sampling frequency). For example, ADC: Passband
Note 14. The calculated delay time is resulting from digital filtering. For the ADC, this time is from the input of an analog
Note 15. The reference frequency is 1kHz.
