1 See the Typical Performance Characteristics section for the offset voltage vs. supply.
2 The input stage uses PNP transistors; therefore, input bias current always flows out of the device.
3 For G > 1, errors from External Resistor R1 and External Resistor R2 should be considered in addition to these specifications, including error from FB pin bias current.
4 Minimum positive supply voltage indicated for V+IN, V−IN, and VREF = 0 V. With V+IN, V−IN, and VREF = −VS, minimum supply is ±1.35 V.
5 See the Typical Performance Characteristics section for operation between 85°C and 125°C.
