Includes amplifier voltage and current noise, as well as noise of internal resistors.
2
Includes input bias and offset current errors.
3
See Figure 7 for CMRR vs. temperature.
4
The input voltage range is a function of the voltage supplies, reference voltage, and ESD diodes. When operating on other supply voltages, see the Absolute Maximum
Ratings section, Figure 11, and Table 5 for more information.
5
Internal resistors are trimmed to be ratio matched but have ±20% absolute accuracy.
