AD8129ARZ-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 | +IN | input | Non-inverting differential input, high impedance and matched to −IN, with a common-mode input range of ±10.5 V at ±12 V supplies. |
| 2 | −VS | power_in | Negative supply pin; total supply voltage range is ±2.25 V to ±12.6 V (single supply +4.5 V to +12.6 V per the features list). |
| 3 | PD | input | Power-down pin referenced to +VS: a logic low (VIL = +VS − 2.5 V max) powers the part down, and VIH is +VS − 1.5 V min. |
| 4 | REF | input | Reference input that sets the output offset level; it is tied to ground for a ground-referenced output and is a high-impedance input (input bias current ±1 µA typ). |
| 5 | FB | input | Feedback input, which receives the output through the external feedback network (RF/RG) and should be kept a few millimeters away from the ground plane to preserve gain flatness. |
| 6 | OUT | output | Amplifier output that directly drives loads down to 100 Ω and provides the signal fed back to FB through the external network. |
| 7 | +VS | power_in | Positive supply pin; it is also the reference level for the PD input, with supply bypassing of 0.01 µF to 0.1 µF recommended close to the pin. |
| 8 | −IN | input | Inverting differential input, high impedance and matched to +IN, with a common-mode input range of ±10.5 V at ±12 V supplies. |
