AD8223ARZ-R7 from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | -RG | passive | Gain resistor terminal; a single resistor between -RG and +RG sets the gain as G = 5 + (80 kΩ/RG), and with no resistor the gain defaults to 5. |
| 2 | -IN | input | Negative differential input of the instrumentation amplifier, which can see common-mode voltages up to 150 mV below the negative supply. |
| 3 | +IN | input | Positive differential input of the instrumentation amplifier, which can see common-mode voltages up to 150 mV below the negative supply. |
| 4 | -VS | power_in | Negative supply pin; connect to 0 V for single-supply operation or to the negative rail for dual-supply operation. |
| 5 | REF | input | Reference terminal to which the output is referenced; connect it to a low impedance source. |
| 6 | OUT | output | Amplifier output, which swings rail-to-rail and is referenced to the REF pin. |
| 7 | +VS | power_in | Positive supply pin; the part operates from +3 V to +24 V single-supply or ±2 V to ±12 V dual-supply. |
| 8 | +RG | passive | Gain resistor terminal; the other side of the external gain resistor connects here together with -RG. |
