AD8422BRMZ-R7 from Analog Devices, in a MSOP-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 with input impedance 200 GΩ |
| 2 | RG | passive | Gain setting resistor terminal; place resistor across pins 2 and 3 to set gain G = 1 + (19.8 kΩ/RG) with minimum value RG = 19.8 Ω. |
| 3 | RG | passive | Gain setting resistor terminal; place resistor across pins 2 and 3 to set gain G = 1 + (19.8 kΩ/RG) with minimum value RG = 19.8 Ω. |
| 4 | +IN | input | Positive input terminal with input impedance 200 GΩ |
| 5 | -VS | power_in | Negative power supply terminal; operating range ±2.3 V to ±18 V dual supply or 4.6 V to 36 V single supply. |
| 6 | REF | input | Reference voltage terminal for output level shifting with voltage range −VS to +VS, input impedance 20 kΩ, input current 35-50 µA, and required source impedance below 1 Ω. |
| 7 | VOUT | output | Output terminal with rail-to-rail swing capability and short-circuit current protection 20 mA. |
| 8 | +VS | power_in | Positive power supply terminal; operating range ±2.3 V to ±18 V dual supply or 4.6 V to 36 V single supply, with quiescent current 338-368 µA. |
