AD8422ARZ-R7 from Analog Devices, in a SOIC-8. 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 | −IN | input | Negative input terminal; input voltage range −VS + 1.2 to +VS − 1.2 V. |
| 2 | RG | passive | Gain setting terminal; place resistor across RG pins to set gain according to G = 1 + (19.8 kΩ/RG) for gains from 1 to 1000. |
| 3 | RG | passive | Gain setting terminal; place resistor across RG pins to set gain according to G = 1 + (19.8 kΩ/RG) for gains from 1 to 1000. |
| 4 | +IN | input | Positive input terminal; input voltage range −VS + 1.2 to +VS − 1.2 V. |
| 5 | −VS | power_in | Negative power supply terminal; ±2.3 V to ±18 V dual-supply or 4.6 V to 36 V single-supply operation. |
| 6 | REF | input | Reference voltage terminal; voltage range −VS to +VS but must not exceed ±VS by more than 0.3 V, use low impedance source below 1 Ω. |
| 7 | VOUT | output | Output terminal; rail-to-rail output with output swing −VS + 0.2 to +VS − 0.2 V at 10 kΩ load. |
| 8 | +VS | power_in | Positive power supply terminal; ±2.3 V to ±18 V dual-supply or 4.6 V to 36 V single-supply operation. |
