HX2342-S from ZHHXDZ, 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 | Inverting input of amplifier A; the voltage range is from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 3 | +INA | input | Non-inverting input of amplifier A; it has the same voltage range as -INA, from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 4 | -Vs | power_in | Negative power supply; the single-supply operating range is 2.5 V to 5.5 V from 0 to 70 °C, or 2.0 V to 5.5 V from -40 to +125 °C. |
| 5 | +INB | input | Non-inverting input of amplifier B; it has the same voltage range as -INB, from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 6 | -INB | input | Inverting input of amplifier B; the voltage range is from (VS- - 0.1 V) to (VS+ + 0.1 V). |
| 7 | OUTB | output | Amplifier B output. |
| 8 | +Vs | power_in | Positive power supply; the absolute maximum supply voltage VS+ to VS- is 10.0 V. |
