1 Total RTI noise = √eNI2 + (eNO/G)2
2 Total RTI VOS = (VOSI) + (VOSO/G).
3 Gain does not include the effects of the external resistor, RG.
4 One input grounded. G = 1.
5 Output current limited at cold temperatures. See Figure 35.
6 See Typical Performance Characteristics for expected operation between 85°C and 125°C.
