AD8428BRZ 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 | Negative input terminal; voltage must not exceed ±VS and differential input is limited to ±1 V without protection resistors. |
| 2 | -FIL | passive | Negative filter terminal giving access between R3 and R4 of the internal node between first and second stages; voltage must not exceed ±VS. |
| 3 | +FIL | passive | Positive filter terminal giving access between R5 and R6 of the internal node between first and second stages; voltage must not exceed ±VS. |
| 4 | +IN | input | Positive input terminal; voltage must not exceed ±VS and differential input is limited to ±1 V without protection resistors. |
| 5 | -VS | power_in | Negative power supply terminal for a supply range of ±4 V to ±18 V, decoupled with a 0.1 µF capacitor close to the pin. |
| 6 | REF | input | Reference voltage terminal to be driven from a low impedance source (well below 1 Ω) to level-shift the output, and should not exceed +VS or -VS. |
| 7 | OUT | output | Output terminal with short-circuit current of 30 mA and indefinite short-circuit duration. |
| 8 | +VS | power_in | Positive power supply terminal for a supply range of ±4 V to ±18 V, decoupled with a 0.1 µF capacitor close to the pin. |
