Noise Performance
The ISL26132 and ISL26134 provide excellent noise
performance. The noise performance on each of the gain
settings of the PGA at the selected word rates is shown in
Resolution in bits decreases by 1-bit if the ADC is operated as a
single-ended input device. Noise measurements are
input-referred, taken with bipolar inputs under the specified
operating conditions, with fCLK = 4.9152MHz.

NOTES:
10. The peak-to-peak noise number is 6.6 times the rms value. This
encompasses 99.99% of the noise excursions that may occur. This
value best represents the worst case noise that could occur in the
output conversion words from the converter.
11. Noise-Free Bits is defined as: Noise-Free Bits = ln(FSR/peak-to-peak
noise)/ln(2) where FSR is the full scale range of the converter,
VREF/Gain.
