HGSEMI · Operational Amplifier · SOP-8
OP27CM 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 | VOS TRIM | passive | Optional offset null pin; an offset nulling resistor (e.g. 20kΩ) is placed between pins 1 and 8. |
| 2 | -IN | input | Inverting input of the amplifier, with a voltage range from -Vs to +Vs. |
| 3 | +IN | input | Non-inverting input of the amplifier, with the same voltage range as -IN. |
| 4 | V- | power_in | Negative power supply or ground; if not grounded, bypass with a 0.1µF capacitor placed as close to the part as possible. |
| 5 | NC | unconnected | No connection. |
| 6 | OUT | output | Amplifier output, with a voltage range extending to within millivolts of each supply rail. |
| 7 | V+ | power_in | Positive power supply (±2.25V to ±18V supplies, 36V max total); place a 0.1µF bypass capacitor as close to the part as possible. |
| 8 | VOS TRIM | passive | Optional offset null pin; an offset nulling resistor (e.g. 20kΩ) is placed between pins 1 and 8. |
