Total RTI Noise = √eNI2 + (eNO/G)2

Total RTI VOS = (VOSI) + (VOSO/G).

Gain does not include the effects of the external resistor, RG.

One input grounded. G = 1.

Only specified to guarantee linear output voltage. If linear bias current is required, use the following voltage range: −VS + 2 V to +VS − 2.2 V. See Figure 19 and

Figure 20.

Output current limited at cold temperatures. See Figure 34.
