LMV551QDCKRQ1

Texas Instruments · Operational Amplifier · SC-70-5

LMV551QDCKRQ1 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; differential input range ±2.5V, common-mode range 0V to V+ rail.
2 V- power_in Negative power supply; supply voltage (V+ - V-) 2.7V to 5.5V, operating temperature -40°C to 125°C.
3 -IN input Inverting input; differential input range ±2.5V, common-mode range 0V to V+ rail.
4 OUT output Output pin; rail-to-rail stage with 70mV typical swing from supply rails into 100kΩ load.
5 V+ power_in Positive power supply; supply voltage (V+ - V-) 2.7V to 5.5V with typical quiescent current 37µA at 25°C.
