AD829JRZ-REEL 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 | OFFSET_NULL | input | Offset null trim pin. Used with pin 8 and an external potentiometer wiper returned to -Vs to trim input offset voltage. |
| 2 | -IN | input | Inverting analog input to the op amp. Differential input resistance is ~13 kΩ, common-mode input range extends to -13.8 V on ±15 V supplies. |
| 3 | +IN | input | Non-inverting analog input to the op amp. Symmetric with -IN; input voltage noise 1.7 nV/√Hz, input bias current 3.3 μA typical. |
| 4 | -VS | power_in | Negative supply rail. Operating range ±4.5 V to ±18 V (measured from ground); typical -15 V. Quiescent current ~5.3 mA on ±15 V supplies. |
| 5 | CCOMP | passive | External compensation pin. A capacitor from this pin to -Vs sets the closed-loop compensation, allowing the user to tailor bandwidth/stability for gains from 1 to 20 (e.g. 30 pF for typical video service). Can also be used to clamp the output. |
| 6 | OUTPUT | output | Op amp output. ±3 V swing into 150 Ω load; ±13.3 V typical into 1 kΩ on ±15 V supplies. Short-circuit current 32 mA. Output short-circuit duration indefinite. |
| 7 | +VS | power_in | Positive supply rail. Operating range ±4.5 V to ±18 V; typical +15 V. Absolute maximum supply voltage ±18 V. |
| 8 | OFFSET_NULL | input | Offset null trim pin. Used with pin 1 and an external potentiometer (wiper returned to -Vs) to trim input offset voltage. |
