Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | −RG | passive | Inverting terminal of external gain-setting resistor RG; with pin 8 forms gain network G = 1 + (100 kΩ/RG). |
| 2 | −IN | input | Inverting in-amp input; input impedance 2 GΩ |
| 3 | +IN | input | Noninverting in-amp input; input impedance 2 GΩ |
| 4 | −VS | power_in | Negative supply terminal; accepts voltage from −6 V to 0 V (single supply) or −2.5 V to −6 V (dual supply). |
| 5 | REF | input | In-amp output reference input; voltage input (−VS to +VS) establishes the common-mode voltage of the output; input impedance 100 kΩ ± 20%. |
| 6 | OUTPUT | output | In-amp output; provides rail-to-rail output swing within 0.2 V of supplies (RL = 10 kΩ). |
| 7 | +VS | power_in | Positive supply terminal; accepts voltage from +3 V to +12 V (single supply) or +2.5 V to +6 V (dual supply). |
| 8 | +RG | passive | Noninverting terminal of external gain-setting resistor RG; with pin 1 forms gain network G = 1 + (100 kΩ/RG). |
