NOTE 4: The test condition is a 1020-Hz input signal with an 8-kHz conversion rate. Input and output common mode is 2.5 V for 5-V supply and
1.5 V for 3.3-V supply. The output configuration is in a 5 V differential-ended mode.

NOTE 5: The filter gain outside of the passband is measured with respect to the gain at 1020 Hz. The input signal is the digital equivalent of a
sine wave (digital full scale = 0 dB). The –3 dB pass band is 0 to 3600 Hz for an 8-kHz sample rate. This pass band scales linearly
with the sample rate.
