**Analog Devices** · Video Amplifiers · SOIC-8

AD829JRZ-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 | OFFSET_NULL | input | Offset null trim pin. Connect a potentiometer between Pin 1 and Pin 8 with the wiper to -Vs to trim input offset voltage (typ 0.2 mV, max 1 mV at 25 degC). |
| 2 | -IN | input | Inverting input of the op amp. Differential input resistance ~13 kOhm, common-mode input capacitance ~1.5 pF. Input bias current typ 3.3 uA. |
| 3 | +IN | input | Non-inverting input of the op amp. Symmetrical to -IN. Input common-mode range typ -13.8 V to +14.3 V on +/-15 V supplies. |
| 4 | -VS | power_in | Negative supply rail. Operating range +/-4.5 V to +/-18 V (i.e., -Vs from -4.5 V to -18 V). Absolute maximum supply voltage +/-18 V. Quiescent current typ 5.3 mA at +/-15 V. |
| 5 | CCOMP | passive | External compensation pin. Connect a compensation capacitor from CCOMP to -Vs (typ 30 pF for differential gain/phase specs; 0 pF for gain of 20). Selecting CCOMP trades bandwidth for stability across gains of 1 to 20; can also be used to clamp the output. |
| 6 | OUTPUT | output | Op amp output. Output swing typ +/-13.3 V into 1 kOhm and +/-12.2 V into 500 Ohm on +/-15 V supplies. Short-circuit current typ 32 mA; output short-circuit duration is indefinite. |
| 7 | +VS | power_in | Positive supply rail. Operating range +4.5 V to +18 V. Absolute maximum supply voltage +/-18 V. Bypass locally with 0.1 uF ceramic near the pin. |
| 8 | OFFSET_NULL | input | Offset null trim pin. Pair with Pin 1 across an external potentiometer whose wiper returns to -Vs to null input offset voltage. |
