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. |
