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. |
