LMV7219 High-Speed Comparator

@@ -0,0 +1,47 @@+# LMV7219++**Texas Instruments** · Comparator · SOT-23-5++The LMV7219 is a high-speed comparator with 7 ns propagation delay and a push-pull rail-to-rail output that needs no pull-up. It runs from a single 2.7 V to 5 V supply, suiting zero-crossing detection, pulse shaping, and fast level triggering in a compact SOT-23-5.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT | output | Comparator push-pull rail-to-rail output. Swings from V- to V+; 7 ns propagation delay, 1.3 ns rise/fall time; sourcing/sinking short-circuit current 20 mA. |+| 2 | V- | power_in | Negative supply pin. Tie to GND for single-supply operation; supply span (V+ - V-) is 2.7 V to 5 V (5.5 V absolute max). |+| 3 | +IN | input | Non-inverting comparator input. Common-mode range extends 200 mV below V- up to V+ - 1.2 V; input bias current 450 nA typical. |+| 4 | -IN | input | Inverting comparator input. Same common-mode range and bias-current characteristics as +IN; differential input voltage rated up to ±supply voltage. |+| 5 | V+ | power_in | Positive supply pin. 2.7 V to 5 V recommended (5.5 V absolute max); typical supply current 1.1 mA at 5 V (0.9 mA at 2.7 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Single high-speed comparator |+| Propagation delay | 7 ns typ |+| Output | Push-pull (rail-to-rail) |+| Supply voltage | 2.7 V to 5 V single |+| Supply current | 1 mA typ |+| Operating temperature | -40 C to 125 C |++## Ordering variants++- `LMV7219DBV`+- `LMV7219DCK`++## CAD (KiCad official)++- Symbol: `lmv7219.kicad_sym`+- Footprint: `lmv7219.kicad_mod`+- 3D model: SOT-23-5 body from KiCad `Package_TO_SOT_SMD/SOT-23-5`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lmv7219.pdf) (29 pp, sha256 `a235b43f905ac80a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
