LMV321AIM5

HGSEMI · Operational Amplifier · SOT-23-5

LMV321AIM5 from HGSEMI, in a SOT-23-5. 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 +IN input Non-inverting input of the amplifier; rail-to-rail common-mode range extends 100 mV beyond either supply rail.
2 -VS power_in Negative supply (ground in single-supply use); the supply range VS+ to VS- is 1.8 V to 5.5 V operating, 10.0 V absolute maximum.
3 -IN input Inverting input of the amplifier; rail-to-rail common-mode range extends 100 mV beyond either supply rail.
4 OUT output Rail-to-rail amplifier output that can drive capacitive loads up to 500 pF and has continuous short-circuit protection.
5 +VS power_in Positive supply; operating range is 1.8 V to 5.5 V relative to VS-, with 10.0 V absolute maximum.
