NOTE 3: The filter gain outside of the passband is measured with respect to the gain at 1020 Hz. The analog input test signal is a sine wave with
0 dB=3 VPP at 5-V supply and 0 db = 2 VPP at 3.3-V supply differential as the reference level for ADC analog input signal. The –3 dB
passband is 0 to 3600 Hz for an 8-kHz sample rate. This passband scales linearly with the sample rate.
