The -B devices provide the best noise specifications.16. Wideband noise aliased into the baseband. Referred to the input. Typical values shown for 25 °C.17. For Peak-to-Peak Noise multiply by 6.6 for all ranges and output rates.18. Word rates and -3dB points with FRS = 0. When FRS = 1, word rates and -3dB points scale by 5/6.TYPICAL NOISE FREE RESOLUTION(BITS), CS55<strong>32</strong>/<strong>34</strong>-BS (See Notes 19 and 20)Output Word -3 dB FilterInstrumentation Amplifier GainRate (Sps) Frequency (Hz) x64 x<strong>32</strong> x16 x8 x4 x2 x17.5 1.94 20 21 22 23 23 23 2315 3.88 20 21 22 22 22 22 2230 7.75 19 20 21 22 22 22 2260 15.5 19 20 21 21 21 21 21120 31 18 19 20 21 21 21 21240 62 17 17 18 18 18 18 18480 122 17 17 17 17 17 17 17960 230 16 16 17 17 17 17 171,920 390 16 16 16 16 16 16 163,840 780 13 13 13 13 13 13 1319. Noise Free Resolution listed is for Bipolar operation, and is calculated as LOG((Input Span)/(6.6xRMSNoise))/LOG(2) rounded to the nearest bit. For Unipolar operation, the input span is 1/2 as large, so onebit is lost. The input span is calculated in the analog input span section of the data sheet. The NoiseFree Resolution table is computed with a value of 1.0 in the gain register. Values other than 1.0 will scalethe noise, and change the Noise Free Resolution accordingly.20. “Noise Free Resolution” is not the same as “Effective Resolution”. Effective Resolution is based on theRMS noise value, while Noise Free Resolution is based on a peak-to-peak noise value specified as 6.6times the RMS noise value. Effective Resolution is calculated as LOG((Input Span)/(RMSNoise))/LOG(2).Specifications are subject to change without notice.DS289PP5 9
