APPLICATIONS INFORMATION
OSR, the noise performance of the device is 200nVRMSwith
better than 80dB rejection of 50Hz ±2% and 60Hz ±2%.
Since the OSR is large (32,768) the wide band rejection
is extremely large and the antialiasing requirements are
simple. The rst multiple of fS occurs at 55Hz 32,768 =
1.8MHz, see Figure 13.
The rst NULL becomes fN = 7.04kHz with an OSR of 256
(an output rate of 880Hz) and fO grounded. While the NULL
has shifted, the sample rate remains constant. As a result
of constant modulator sampling rate, the linearity, offset
and full-scale performance remains unchanged as does
the rst multiple of fS.
