OPA2333 Zero-Drift Op-Amp

@@ -0,0 +1,53 @@+# OPA2333++**Texas Instruments** · Operational Amplifier · SOIC-8++The OPA2333 is a dual micropower CMOS operational amplifier that uses zero-drift (chopper) techniques to achieve low input offset voltage (10 uV max) and near-zero drift over temperature. With rail-to-rail input and output on a single 1.8 V to 5.5 V supply, it suits precision bridge, thermocouple, and current-sense front ends.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT A | output | Output of channel A operational amplifier. Rail-to-rail output, swings within 50 mV of the supply rails. |+| 2 | -IN A | input | Inverting input of channel A. Rail-to-rail input, common-mode range extends 100 mV beyond each supply rail. Input current limited to <10 mA if driven beyond rails. |+| 3 | +IN A | input | Noninverting input of channel A. Rail-to-rail input, common-mode range extends 100 mV beyond each supply rail. |+| 4 | V- | power_in | Negative (lowest) power supply. Typically ground in single-supply operation, or the negative rail in dual-supply operation. Total supply (V+) - (V-) must be between 1.8 V and 5.5 V. |+| 5 | +IN B | input | Noninverting input of channel B. Rail-to-rail input, common-mode range extends 100 mV beyond each supply rail. |+| 6 | -IN B | input | Inverting input of channel B. Rail-to-rail input, common-mode range extends 100 mV beyond each supply rail. Input current limited to <10 mA if driven beyond rails. |+| 7 | OUT B | output | Output of channel B operational amplifier. Rail-to-rail output, swings within 50 mV of the supply rails. |+| 8 | V+ | power_in | Positive (highest) power supply. 1.8 V to 5.5 V single-supply, or ±0.9 V to ±2.75 V dual-supply. Bypass with 0.1 µF ceramic capacitor to V-. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Dual zero-drift CMOS op-amp |+| Input offset voltage | 10 uV max |+| Offset drift | 0.05 uV/C typ |+| Gain-bandwidth product | 350 kHz typ |+| Supply voltage | 1.8 V to 5.5 V |+| Supply current | 17 uA/amp typ |+| Input/output | Rail-to-rail |+| Operating temperature | -40 C to 125 C |++## Ordering variants++- `OPA2333D`+- `OPA2333DGK`+- `OPA2333DRB`++## CAD (KiCad official)++- Symbol: `opa2333.kicad_sym`+- Footprint: `opa2333.kicad_mod`+- 3D model: SOIC-8 body from KiCad `Package_SO/SOIC-8_3.9x4.9mm_P1.27mm`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/opa2333.pdf) (49 pp, sha256 `df60da7154848c57`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
