NOTES:
1. θ
1. Apply 0V across V
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
3. For applications where low input pin 10 is not operated at pin 7 potential, a return path of not more than 100kΩ resistance must be provided
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,
