Its output swings rail to rail, it works from a single 2.7 to 5.5 V supply, and its 1 MHz gain-bandwidth and 1 V/us slew rate cover sensor buffering, filtering, and level scaling. Because it comes one-per-package it fits a single gain stage without wasting half of a dual op-amp. Pinout is IN+, GND (V-), IN-, OUT, VCC+ (V+).++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | 1IN+ | input | Noninverting input of the op-amp. Input voltage range −0.2 V to 5.7 V (absolute max); common-mode range specified from V− to (V+ − 1 V). High input impedance analog input. |+| 2 | GND | power_in | Negative supply / ground. Connects to 0 V for single-supply operation (VCC+ from 2.7 V to 5.5 V) or to V− for split-supply operation. |+| 3 | 1IN− | input | Inverting input of the op-amp. Differential input voltage rating ±5.5 V with respect to IN+. High input impedance analog input. |+| 4 | OUT | output | Rail-to-rail op-amp output. Short-circuit current typically 40 mA sourcing/sinking. Can swing to within a few mV of both supply rails under light load. |+| 5 | VCC+ | power_in | Positive supply pin. Recommended operating range 2.7 V to 5.5 V (5.5 V absolute maximum). Decouple with a 0.1 µF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Single low-voltage op-amp |+| Output | rail-to-rail |+| Gain-bandwidth | 1 MHz |+| Slew rate | 1 V/µs |+| Supply voltage | 2.7-5.5 V |+| Input range | includes ground |+| Quiescent current | ~130 µA |+| Package | SOT-23-5 |++## Ordering variants++- `LMV321IDBVR (SOT-23-5)`+- `LMV321IDCKR (SC-70-5)`++## CAD (KiCad official)++- Symbol: `Amplifier_Operational:LMV321`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lmv321.pdf) (53 pp, sha256 `05e7739c25379268`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
