2. Linearity is measured as a difference from a straight line drawn through zero and positive full scale. Limits do not include

±0.5 count bit

digitizing error.

3. For applications where low input pin 10 is not operated at pin 7 potential, a return path of not more than 100k

Ω resistance must be provided

for input bias currents.

4. The common mode input voltage above ground cannot exceed +0.2V if the full input signal range of 999mV is required at pin 11. That is,

pin 11 may not operate higher than 1.2V positive with respect to ground or 0.2V negative with respect to ground. If the maximum input

signal is less than 999mV, the common mode input voltage may be raised accordingly.
