Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | RG | passive | Gain-setting pin. Place external gain resistor RG between pin 1 and pin 8 for gains greater than 5 V/V. Gain equation: G = 5 + 80kΩ/RG. |+| 2 | V-IN | input | Inverting (negative) differential input to the instrumentation amplifier. Input signal voltage limited to (V-)-0.7 V to (V+)+0.7 V by internal protection diodes. |+| 3 | V+IN | input | Non-inverting (positive) differential input to the instrumentation amplifier. Input signal voltage limited to (V-)-0.7 V to (V+)+0.7 V by internal protection diodes. |+| 4 | V- | power_in | Negative supply rail. Total supply voltage V+ to V- range ±1.35 V to ±18 V (36 V max). May be tied to GND for single-supply operation. |+| 5 | Ref | input | Output reference input. Must be driven by a low-impedance source or tied to ground; sets the DC reference for the output (VO = (V+IN - V-IN)·G + VRef). |+| 6 | VO | output | Amplifier output. Delivers the amplified differential input signal referred to the Ref pin. |+| 7 | V+ | power_in | Positive supply rail. Total supply voltage V+ to V- range ±1.35 V to ±18 V (36 V max). |+| 8 | RG | passive | Gain-setting pin. Place external gain resistor RG between pin 1 and pin 8 for gains greater than 5 V/V.
