AD8479ARZ-RL 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 | REF(-) | input | Negative reference input, which must be grounded (or tied to the same low-impedance ground plane as REF(+)) for unity gain, otherwise common-mode rejection degrades; it is limited to −VS − 0.3 V to +VS + 0.3 V. |
| 2 | -IN | input | Inverting input of the differential amplifier, with a common-mode range of ±600 V and a maximum differential input of ±14.7 V. |
| 3 | +IN | input | Noninverting input of the differential amplifier, with a common-mode range of ±600 V and a maximum differential input of ±14.7 V. |
| 4 | -VS | power_in | Negative supply voltage; the part operates from ±2.5 V to ±18 V supplies, and each supply pin should be decoupled with a 0.1 µF capacitor placed close to the pin. |
| 5 | REF(+) | input | Positive reference input that sets the output reference level, which must be grounded (or tied to the same low-impedance ground plane as REF(-)) for unity gain and is limited to −VS − 0.3 V to +VS + 0.3 V. |
| 6 | OUTPUT | output | Single-ended output, measured relative to REF(-) and REF(+), with a short-circuit current of ±55 mA and stable operation for capacitive loads up to 500 pF. |
| 7 | +VS | power_in | Positive supply voltage; the part operates from ±2.5 V to ±18 V supplies (absolute maximum ±18 V), and each supply pin should be decoupled with a 0.1 µF capacitor placed close to the pin. |
| 8 | NC | unconnected | No connect; do not connect this pin. |
