AD8422BRZ-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 differential input with input impedance 200 GΩ |
| 2 | RG | passive | Gain setting resistor terminal; connect external resistor to set gain per formula G = 1 + (19.8 kΩ/RG). |
| 3 | RG | passive | Gain setting resistor terminal; connect external resistor to set gain per formula G = 1 + (19.8 kΩ/RG). |
| 4 | +IN | input | Positive differential input with input impedance 200 GΩ |
| 5 | -VS | power_in | Negative supply voltage pin; −1.8 V to −18 V dual supply or 0 V reference for single supply operation with maximum rated voltage ±1.8 V to ±18 V. |
| 6 | REF | input | Reference voltage input pin for output DC offset adjustment; voltage range ±VS ± 0.3 V, requires low impedance source below 1 Ω for best performance. |
| 7 | VOUT | output | Output voltage pin with rail-to-rail swing from −VS + 0.2 to +VS − 0.2 V at 10 kΩ load and continuous short-circuit current protection at 20 mA. |
| 8 | +VS | power_in | Positive supply voltage pin; +1.8 V to +18 V dual supply or 3.6 V to 36 V single supply operation with maximum rated voltage ±1.8 V to ±18 V. |
