12. Wideband noise aliased into the baseband. Referred to the input. Typical values shown for 25 °C.
13. For Peak-to-Peak Noise multiply by 6.6 for all ranges and output rates.
14. Word rates and -3dB points with FRS = 0. When FRS = 1, word rates and -3dB points scale by 5/6.
15. Noise-free resolution listed is for bipolar operation, and is calculated as LOG((Input Span)/(6.6xRMS
16. “Noise-free resolution” is not the same as “effective resolution”. Effective resolution is based on the
Noise))/LOG(2) rounded to the nearest bit. For unipolar operation, the input span is 1/2 as large, so one
bit is lost. The input span is calculated in the analog input span section of the data sheet. The noise-free
resolution table is computed with a value of 1.0 in the gain register. Values other than 1.0 will scale the
noise, and change the noise-free resolution accordingly.
RMS noise value, while noise-free resolution is based on a peak-to-peak noise value specified as 6.6
times the RMS noise value. Effective resolution is calculated as LOG((Input Span)/(RMS
Noise))/LOG(2).
