HX2342-S

ZHHXDZ · Operational Amplifier · SOP-8

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.
