HGSEMI · Operational Amplifier · SOP-8
OPA374M 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 connect pin on the OPA374 SOP-8 package. |
| 2 | INA- | input | Inverting input of the amplifier; input range limited to VSS-0.1V to VDD+0.1V for normal operation (absolute max VSS-0.5V to VDD+0.5V). |
| 3 | INA+ | input | Non-inverting input of the amplifier; input range limited to VSS-0.1V to VDD+0.1V for normal operation (absolute max VSS-0.5V to VDD+0.5V). |
| 4 | VSS | power_in | Negative supply or ground; supply span VDD to VSS is 2.1V to 5.5V (absolute max 7.5V). |
| 5 | NC | unconnected | No connect pin on the OPA374 SOP-8 package. |
| 6 | OUT | output | Amplifier output with rail-to-rail swing, minimum 53mA output current at 25°C. |
| 7 | VDD | power_in | Positive supply, 2.1V to 5.5V single supply; place a 0.1µF ceramic capacitor close to this pin. |
| 8 | NC | unconnected | No connect pin on the OPA374 SOP-8 package. |
