OPA365

@@ -0,0 +1,50 @@+# OPA365++**Texas Instruments** · Operational amplifier · SOT-23-5++Rail-to-rail op-amp whose input stage has no crossover region, so it keeps low distortion and a flat offset all the way across the common-mode range, unlike ordinary rail-to-rail parts that glitch mid-swing. A 50 MHz gain-bandwidth and 4.5 nV/rtHz noise suit it to driving precision ADCs and buffering single-supply sensor signals from 2.2 to 5.5 V. A 100 uV offset and 25 V/us slew round it out. The single of the OPA365/2365 family.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VOUT | output | Amplifier output. Rail-to-rail; typical swing within 10 mV of either supply rail with a 10 kΩ load. Short-circuit protected to ground (continuous). |+| 2 | V- | power_in | Negative (lowest) power supply. Typically GND in single-supply operation, or the negative rail in split-supply operation. Total supply range (V+) - (V-) = 2.2 V to 5.5 V. |+| 3 | +IN | input | Positive (noninverting) op-amp input. Rail-to-rail common-mode range extending 100 mV beyond each supply rail. Input bias current typ 0.2 pA; CMOS gate, high impedance. |+| 4 | -IN | input | Negative (inverting) op-amp input. Rail-to-rail common-mode range extending 100 mV beyond each supply rail. Input bias current typ 0.2 pA; CMOS gate, high impedance. |+| 5 | V+ | power_in | Positive (highest) power supply. 2.2 V to 5.5 V referenced to V-. Bypass to V- with a 0.1 µF ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Zero-crossover rail-to-rail op-amp |+| Gain-bandwidth | 50 MHz |+| Input voltage noise | 4.5 nV/rtHz |+| Input offset | 100 uV (typ) |+| Slew rate | 25 V/us |+| Supply | 2.2-5.5 V |+| Output | Rail-to-rail |+| Package | SOT-23-5 |++## Ordering variants++- `OPA365AIDBVR (SOT-23-5)`+- `OPA365AID (SO-8)`+- `OPA2365AIDR (dual, SO-8)`++## CAD (KiCad official)++- Symbol: `Amplifier_Operational:OPA365xxDBV (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/opa365.pdf) (36 pp, sha256 `a241cc6985db2bc7`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
