HXY MOSFET · Operational Amplifier · SOP-8
HOPA2340UA from HXY MOSFET, 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 | OUTA | output | Amplifier A output. |
| 2 | -INA | input | Amplifier A inverting input; voltage range can go from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 3 | +INA | input | Amplifier A non-inverting input; same voltage range as -IN, from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 4 | -VS | power_in | Negative supply, normally tied to ground, may be tied to another voltage as long as VS+ to VS- is 2.1 V to 5.5 V. |
| 5 | +INB | input | Amplifier B non-inverting input; same voltage range as -IN, from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 6 | -INB | input | Amplifier B inverting input; voltage range can go from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 7 | OUTB | output | Amplifier B output. |
| 8 | +VS | power_in | Positive supply, 2.1 V to 5.5 V; split supplies are possible as long as VS+ to VS- is between 2.1 V and 5.5 V. |
