It runs on a single or dual supply from 3 to 15 V and holds accuracy across the full input range. The wide supply span and low bias make it a common choice for pH probes, photodiodes, and other high-impedance front ends. A classic general-purpose CMOS dual.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT A | output | Output for amplifier A. Rail-to-rail output swing within 20mV of either supply on 100kΩ load; specified for 2kΩ and 600Ω loads. Max output current ±30mA (absolute max). |+| 2 | -IN A | input | Inverting input for amplifier A. CMOS input with ultra-low 20fA typical input bias current and 10TΩ input resistance. Absolute max input current ±5mA. |+| 3 | +IN A | input | Noninverting input for amplifier A. Rail-to-rail common-mode input voltage range (V- to V+). CMOS input with 20fA typical bias current. |+| 4 | V- | power_in | Negative supply voltage input (or GND in single-supply operation). Supply voltage VS = (V+) - (V-) from 3V (min) to 15.5V (nom max), 16V absolute max. Max supply pin current 40mA. |+| 5 | +IN B | input | Noninverting input for amplifier B. Rail-to-rail common-mode input voltage range. CMOS input, 20fA typical bias current, 10TΩ input resistance. |+| 6 | -IN B | input | Inverting input for amplifier B. CMOS input with 20fA typical bias current. Absolute max input current ±5mA. |+| 7 | OUT B | output | Output for amplifier B. Rail-to-rail output swing within 20mV of supply on 100kΩ load; drives 2kΩ and 600Ω loads. Absolute max output current ±30mA. |+| 8 | V+ | power_in | Positive supply voltage input. Supply range VS = (V+) - (V-) is 3V to 15.5V (16V absolute max). Do not short output to V+ when V+ > 13V. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Dual CMOS rail-to-rail op-amp |+| Gain-bandwidth | 1.5 MHz |+| Input bias current | 20 fA (typ) |+| Supply | 3-15 V (single or dual) |+| Output | Rail-to-rail |+| Slew rate | 1.3 V/us |+| Package | SOIC-8 |++## Ordering variants++- `LMC6482IM (SOIC-8)`+- `LMC6482AIM (A-grade, SOIC-8)`+- `LMC6482IN (PDIP-8)`++## CAD (KiCad official)++- Symbol: `Amplifier_Operational:LMC6482 (KiCad official)`+- 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/lmc6482.pdf) (50 pp, sha256 `42c848d4af110617`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
