HGA333M5

HGSEMI · Operational Amplifier · SOT23-5L

HGA333M5 from HGSEMI, in a SOT23-5L. 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 OUT output Amplifier output; the datasheet gives the output swing as within 100 mV of the supply rails under normal test conditions and a short-circuit current of ±5 mA.
2 V- power_in Negative supply rail (lowest potential); operating supply range is 1.8 V to 5.5 V total (V+ minus V-).
3 +IN input Non-inverting input; common-mode range extends 0.1 V beyond each supply rail, and input voltages more than 0.3 V beyond the rails require a series resistor limiting input current to 10 mA or less.
4 -IN input Inverting input; same common-mode range (V- - 0.1 V to V+ + 0.1 V) and input-current limit of 10 mA applies as on +IN.
5 V+ power_in Positive supply rail (highest potential); operating supply range is 1.8 V to 5.5 V total (V+ minus V-), absolute maximum 7 V.
