AD820ARZ-REEL7 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 | NC | unconnected | No internal connection; offset null adjust pins are not functional in the SOIC (R) package. |
| 2 | -IN | input | Inverting input; FET input stage with differential input impedance 10¹³ Ω ‖ 0.5 pF, max input bias current 25 pA, max input offset current 20 pA. |
| 3 | +IN | input | Non-inverting input; common-mode range extends 0.2 V below -VS to 1 V below +VS; common-mode input impedance 10¹³ Ω ‖ 2.8 pF. |
| 4 | -VS | power_in | Negative supply rail; 0 V for single-supply operation (+3 V to +36 V total) or -1.5 V to -18 V for dual-supply; absolute maximum supply voltage ±18 V. |
| 5 | NC | unconnected | No internal connection. |
| 6 | VOUT | output | Rail-to-rail output; swings within 5 mV of -VS and 10 mV of +VS at 20 µA load; minimum output current 15 mA; drives up to 350 pF capacitive load. |
| 7 | +VS | power_in | Positive supply rail; +3 V to +36 V single supply or +1.5 V to +18 V dual supply; quiescent current 800 µA max; absolute maximum supply voltage ±18 V. |
| 8 | NC | unconnected | No internal connection; offset null adjust pins are not functional in the SOIC (R) package. |
