**Analog Devices** · Differential OpAmps · SOIC-8

AD8276ARZ 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 | Reference voltage input; the reference must sit within the supply rails, as the positive supply must be at least 2 V above the negative supply and reference voltage. |
| 2 | -IN | input | Inverting input of the difference amplifier, with input voltage range extending beyond the supply rails. |
| 3 | +IN | input | Noninverting input of the difference amplifier, with input voltage range extending beyond the supply rails. |
| 4 | -VS | power_in | Negative supply; dual supplies from ±2 V to ±18 V or single supply from 2.0 V to 36 V are supported. |
| 5 | SENSE | passive | Sense terminal of the amplifier, which is connected to the output's feedback network for the difference amplifier configuration. |
| 6 | OUT | output | Amplifier output; short-circuit current is limited to ±15 mA and capacitive load drive is 200 pF. |
| 7 | +VS | power_in | Positive supply; dual supplies from ±2 V to ±18 V or single supply from 2.0 V to 36 V are supported. |
| 8 | NC | unconnected | No connect; this pin is not internally connected. |
