Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT A | output | Output of amplifier channel A. Rail-to-rail output, capable of sourcing +36mA and sinking -30mA (short-circuit typical). Swings to within 0.2V of the rails at RL=10kOhm. |+| 2 | -IN A | input | Inverting input of amplifier channel A. High-impedance JFET input (~10^13 Ohm || 8pF differential); 20pA max input bias current. |+| 3 | +IN A | input | Non-inverting input of amplifier channel A. High-impedance JFET input; common-mode range extends from (V-)-0.1V to (V+)-3.5V. |+| 4 | V- | power_in | Negative supply rail. Connect to GND for single-supply operation (4.5V to 36V total) or to a negative rail for dual-supply operation (+/-2.25V to +/-18V). |+| 5 | +IN B | input | Non-inverting input of amplifier channel B. High-impedance JFET input; common-mode range extends from (V-)-0.1V to (V+)-3.5V. |+| 6 | -IN B | input | Inverting input of amplifier channel B. High-impedance JFET input; 20pA max input bias current. |+| 7 | OUT B | output | Output of amplifier channel B. Rail-to-rail output, capable of sourcing +36mA and sinking -30mA (short-circuit typical). Swings to within 0.2V of the rails at RL=10kOhm. |+| 8 | V+ | power_in | Positive supply rail. 4.5V to 36V (single-supply) or +/-2.25V to +/-18V (dual-supply). Quiescent current 1.8mA typ, 2.3mA max per amplifier. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `OPA2141AIDR`+- `OPA2141AIDRIDGKR`+- `OPA2141AIDRIDGK`++## CAD (KiCad official)++- Symbol: `OPA2141AIDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (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/opa2141a.pdf) (31 pp, sha256 `4468bbe4c1a9786d`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
