OPA2374MM from HGSEMI, 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 | OUTA | output | Amplifier A output with rail-to-rail swing, able to drive heavy loads (53 mA typical output current at 5V). |
| 2 | INA- | input | Amplifier A inverting input; common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 3 | INA+ | input | Amplifier A non-inverting input; common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 4 | VSS | power_in | Negative supply or ground; supply span VDD to VSS is 2.1V to 5.5V (absolute maximum 7.5V). |
| 5 | INB+ | input | Amplifier B non-inverting input; common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 6 | INB- | input | Amplifier B inverting input; common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 7 | OUTB | output | Amplifier B output with rail-to-rail swing, able to drive heavy loads (53 mA typical output current at 5V). |
| 8 | VDD | power_in | Positive supply, 2.1V to 5.5V single supply, with a 0.1µF ceramic bypass capacitor placed close to the pin. |
