1. LSB stands for Least Significant Bit. One LSB is equal to 305 μV.
2. Not tested.
3. Typical rms noise at worst case transitions and temperatures.
4. Measured with various fixed resistors.
5. For bipolar input ranges, full scale error is the worst case of -Full Scale or +Full Scale untrimmed deviation fromideal first and
last scale code transitions, divided by the transition voltage (not divided by the full-scale range) and includes the effect of offset
error. For unipolar input ranges, full scale error is the deviation of the last code transition divided by the transition voltage. It
also includes the effect of offset error.
