LMV321IDBVR-CN

ChipNobo · Operational Amplifier · SOT-23-5

LMV321IDBVR-CN from ChipNobo, 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 with input common-mode range of -0.1V to 5.6V at V+=5.5V.
2 V- power_in Negative supply (ground) pin; supply voltage V+ to V- is 2.1V to 5.5V recommended, 6V absolute maximum.
3 -IN input Inverting input of the amplifier, rail-to-rail with input common-mode range of -0.1V to 5.6V at V+=5.5V.
4 OUT output Amplifier output with rail-to-rail swing, short-circuit current typically 60mA.
5 V+ power_in Positive supply pin, 2.1V to 5.5V operating range with 40µA typical quiescent current.
