LMV321AQDCKRQ1

Texas Instruments · Operational Amplifier · SC-70-5

LMV321AQDCKRQ1 from Texas Instruments, in a SC-70-5. 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 with common-mode voltage range (V-) - 0.5 V to (V+) + 0.5 V and maximum input current ±10 mA.
2 V- power_in Negative (lowest) supply or ground for single-supply operation.
3 -IN input Inverting input with common-mode voltage range (V-) - 0.5 V to (V+) + 0.5 V and maximum input current ±10 mA.
4 OUT output Output with rail-to-rail swing from V- to V+.
5 V+ power_in Positive (highest) supply voltage with recommended operating range 2.5 V to 5.5 V.
