AD818ARZ-REEL7 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 | NULL | passive | Offset null pin; a 10 kΩ potentiometer between pins 1 and 8 with wiper to -VS gives about ±10 mV null range. |
| 2 | -IN | input | Inverting input; differential input voltage limited to ±6 V, so a series protection resistor is needed for overloads beyond that. |
| 3 | +IN | input | Non-inverting input; differential input voltage limited to ±6 V and common-mode input limited to ±VS. |
| 4 | -VS | power_in | Negative supply (ground in single-supply use); dual supply operating range ±2.5 V to ±18 V, absolute maximum ±18 V. |
| 5 | NC | unconnected | No connect; pin is not internally connected. |
| 6 | OUTPUT | output | Op amp output delivering 50 mA minimum output current and short-circuit current of 90 mA typical at ±15 V. |
| 7 | +VS | power_in | Positive supply; single supply range +5 V to +36 V, absolute maximum ±18 V total dual supply. |
| 8 | NULL | passive | Offset null pin; used with pin 1 and a 10 kΩ potentiometer to trim input offset voltage. |
