Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | −IN | input | Negative input with operating voltage range from −VS − 0.1 V to +VS − 0.8 V at +25°C. |
| 2 | RG | passive | Gain-setting resistor terminal; connect external resistor between pins 2 and 3 to set gain according to G = 1 + (49.4 kΩ/RG) for range 1 to 1000. |
| 3 | RG | passive | Gain-setting resistor terminal; connect external resistor between pins 2 and 3 to set gain according to G = 1 + (49.4 kΩ/RG) for range 1 to 1000. |
| 4 | +IN | input | Positive input with operating voltage range from −VS − 0.1 V to +VS − 0.8 V at +25°C. |
| 5 | −VS | power_in | Negative supply with operating range ±1.35 V to ±18 V for dual-supply operation or 0 V for single-supply operation. |
| 6 | REF | input | Reference terminal with 100 kΩ input impedance and voltage range from −VS to +VS; must be driven from low impedance source below 2 Ω. |
| 7 | VOUT | output | Rail-to-rail output with swing from −VS + 0.4 V to +VS − 0.7 V with 2 kΩ load at +25°C. |
| 8 | +VS | power_in | Positive supply with operating range ±1.35 V to ±18 V for dual-supply operation or 2.2 to 36 V for single-supply operation. |
