LMV321WG from TECH PUBLIC, 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 analog input. Input common-mode voltage range extends from Vss-0.1V to Vdd+0.1V (rail-to-rail). Absolute max is Vss-0.5V to Vdd+0.5V. |
| 2 | -Vs | power_in | Negative supply / ground (Vss). Typically tied to GND for single-supply operation. Vdd-Vss operating range is 2.2V to 5.5V (absolute max 7V). |
| 3 | -IN | input | Inverting analog input. Input common-mode voltage range extends from Vss-0.1V to Vdd+0.1V (rail-to-rail). Input bias current is typically 10pA. |
| 4 | OUT | output | Op-amp output. Rail-to-rail output swing (typ. 6mV from either supply rail with RL=100kΩ). Output short-circuit current is typically ±20mA. |
| 5 | +Vs | power_in | Positive supply (Vdd). Operating range 2.2V to 5.5V (absolute max 7V). Typical quiescent current 40µA at Vdd=5V. |
