@@ -0,0 +1,49 @@+# OPA340++**Texas Instruments** · Operational amplifier · SOT-23-5++Single op-amp with rail-to-rail input and output on a single 2.5 to 5.5 V supply, offering 5.5 MHz of bandwidth with low distortion in a SOT-23-5. It swings to within millivolts of both rails and drives ADC inputs and light loads cleanly, which suits it to single-supply data-acquisition front ends and audio buffering on 3.3 and 5 V boards. A general-purpose rail-to-rail single with more bandwidth than the low-cost commodity parts, the single of the OPA340/2340/4340 family.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT | output | Amplifier output. Rail-to-rail output stage swings within 1 mV of either supply rail with a 100-kOhm load. Short-circuit protected to ground (one amplifier per package). |+| 2 | V- | power_in | Negative (lowest) power supply. Tie to GND for single-supply operation or to a negative rail for dual-supply operation. Total supply span (V+) - (V-) must not exceed 5.5 V. |+| 3 | +IN | input | Positive (noninverting) input. Rail-to-rail input common-mode voltage range extends 500 mV below V- and 500 mV above V+. Input signals swinging more than 0.5 V beyond the rails should be current-limited to <=10 mA (diode-clamped to supplies). |+| 4 | -IN | input | Negative (inverting) input. Rail-to-rail input common-mode voltage range extends 500 mV below V- and 500 mV above V+. Diode-clamped to supplies; limit signal current beyond rails to <=10 mA. |+| 5 | V+ | power_in | Positive (highest) power supply. Operating range 2.7 V to 5.5 V (single supply) with (V+) - (V-) not exceeding 5.5 V. Bypass with 0.1 uF ceramic to V-/GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Single rail-to-rail op-amp |+| Gain-bandwidth | 5.5 MHz |+| Supply | 2.5-5.5 V (single) |+| Output | Rail-to-rail |+| Slew rate | 6 V/us |+| Input offset | 150 uV (typ) |+| Package | SOT-23-5 |++## Ordering variants++- `OPA340NA (SOT-23-5)`+- `OPA340UA (SOIC-8)`+- `OPA2340UA (dual, SOIC-8)`++## CAD (KiCad official)++- Symbol: `Amplifier_Operational:OPA340NA (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/opa340.pdf) (48 pp, sha256 `8099f9f9e8e49c45`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
