**ZJW** · Differential OpAmps · MSOP-8

ZJA3678AUABR from ZJW, in a MSOP-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 input (analog input) that sets the output reference level of the difference amplifier. |
| 2 | -IN | input | Inverting analog input, protected to ±65 V relative to -VS. |
| 3 | +IN | input | Non-inverting analog input, protected to ±65 V relative to -VS. |
| 4 | -VS | power_in | Negative power supply (ground in single-supply use); supply range 2.7 V to 36 V total, 40 V absolute maximum. |
| 5 | SENSE | input | Sense terminal (analog input) for the output feedback connection. |
| 6 | OUT | output | Analog output, short-circuit protection limited by over-temperature protection. |
| 7 | +VS | power_in | Positive power supply; supply range 2.7 V to 36 V total, 40 V absolute maximum. |
| 8 | NC | unconnected | No connect; this pin is not internally connected. |
