OPA379M from HGSEMI, in a SOP-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 | NC | unconnected | No internal connection on the OPA379 SOP-8 package. |
| 2 | -In | input | Inverting input of the amplifier; input common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V), and the op amp is stable for gains of 10 or more. |
| 3 | +In | input | Non-inverting input of the amplifier; input common-mode range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). |
| 4 | V- | power_in | Negative supply (VSS) or ground; for dual-supply operation bypass with a 0.1µF ceramic capacitor, supply range is 1.4V to 5.5V total. |
| 5 | NC | unconnected | No internal connection on the OPA379 SOP-8 package. |
| 6 | Output | output | Rail-to-rail amplifier output that sources or sinks 20mA typical into 10Ω to VS/2. |
| 7 | V+ | power_in | Positive supply (VDD), 1.4V to 5.5V single supply with absolute maximum 7.5V; place a 0.1µF ceramic capacitor close to this pin. |
| 8 | NC | unconnected | No internal connection on the OPA379 SOP-8 package. |
