Noise))/LOG(2) rounded to the nearest bit. For unipolar mode, the number of bits of Noise Free
Resolution is LOG((Input Range)/(6.6xRMS Noise))/LOG(2) rounded to the nearest bit. Also, the
CS5522/24/28’s output conversions are 24 bits. Noise free Resolution numbers are based upon
VREF = 2.5 V and XIN = 32.768 kHz. The values will be affected directly by changes in VREF, but the
effects due to changes in the XIN frequency will be minor.
