NOTE 6: 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 nominal differential DAC channel output with
this input condition is 6 VI(PP). The –1 dB pass band is 0 to 3400 Hz for an 8-kHz sample rate. This pass band
scales linearly with the sample rate.
