NOTES:
1. Apply 0V across V
11
to V
10
. Adjust zero potentiometer to give 000mV reading. Apply 900mV to input and adjust gain potentiometer to
give 900mV reading.
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 100kΩ 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.
