OPA2340MM 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 | Output of amplifier A, rail-to-rail. |
| 2 | INA- | input | Inverting input of amplifier A; keep within VSS-0.5V to VDD+0.5V (abs max). |
| 3 | INA+ | input | Non-inverting input of amplifier A; keep within VSS-0.5V to VDD+0.5V (abs max). |
| 4 | VSS | power_in | Negative supply or ground; single supply 1.8V to 5.5V total, bypass with 0.1µF for dual supply. |
| 5 | INB+ | input | Non-inverting input of amplifier B; keep within VSS-0.5V to VDD+0.5V (abs max). |
| 6 | INB- | input | Inverting input of amplifier B; keep within VSS-0.5V to VDD+0.5V (abs max). |
| 7 | OUTB | output | Output of amplifier B, rail-to-rail. |
| 8 | VDD | power_in | Positive supply, 1.8V to 5.5V operating (7.5V abs max); place a 0.1µF ceramic capacitor close to the pin. |
