LMV551MGX from Texas Instruments, in a SC-70-5. 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 with common mode range 0-2.1V at 3V supply and 0-4.1V at 5V supply; maximum ±2.5V differential input voltage. |
| 2 | V- | power_in | Negative power supply terminal; supports supply voltage differential range of 2.7V to 5.5V from V+. |
| 3 | -IN | input | Inverting input with common mode range 0-2.1V at 3V supply and 0-4.1V at 5V supply; maximum ±2.5V differential input voltage. |
| 4 | OUT | output | Output terminal providing rail-to-rail signal swing with typical 40-100mV offset from supply rails depending on load impedance. |
| 5 | V+ | power_in | Positive power supply terminal; operates at 2.7V to 5.5V with maximum 6V differential from V-. |
