# LMV321M5X

**Texas Instruments** · Operational Amplifier · SOT-23-5

LMV321M5X from Texas Instruments, 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 | Noninverting input to the op-amp. Input common-mode range spans from V- - 0.2 V up to V+ - 0.8 V. |
| 2 | V- | power_in | Negative (lowest) power supply, typically tied to GND for single-supply operation. Supply voltage range 2.7 V to 5.5 V measured between V+ and V-. |
| 3 | -IN | input | Inverting input to the op-amp. Input common-mode range spans from V- - 0.2 V up to V+ - 0.8 V. |
| 4 | OUTPUT | output | Op-amp output. Rail-to-rail swing: with a 10 kOhm load, output swings within ~10 mV of V+ and ~65 mV of V-. |
| 5 | V+ | power_in | Positive (highest) power supply. Supply voltage range 2.7 V to 5.5 V measured between V+ and V-. |
