NOTE:
11. Noise-free resolution in Table 2 is calculated as LOG ((Input Span)/(RMS Noise x 6.6))/LOG(2). The result is rounded to the nearest tenth of a bit. The
Input Span is equivalent to ±0.5VREF/GAIN, VREF = 5V. The RMS noise is selected from Table 1 for the desired Output Word Rate and Gain option.
