LMV321WG-7

MSKSEMI · Operational Amplifier · SOT-23-5

LMV321WG-7 from MSKSEMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN+ input Non-inverting input of the op-amp. Input common-mode voltage range extends from -0.1V to VCC-0.8V.
2 VEE power_in Negative supply / ground rail. Typically tied to 0V in single-supply operation; supply range 2.7V to 5.5V (VCC-VEE).
3 IN- input Inverting input of the op-amp. Typical input bias current 11nA, input offset voltage 1.7mV typ.
4 OUTPUT output Rail-to-rail op-amp output. VOH within 10mV of VCC and VOL within 65mV of VEE under 10kΩ load; output source ~60mA and sink ~160mA typ (short-circuit).
5 VCC power_in Positive supply pin. Operating range 2.7V to 5.5V (absolute max 6V). Supply current 130µA typ at VCC=5V.
