It operates from a single supply (3V to 32V) or dual supplies. A versatile, low-cost op-amp suitable for signal conditioning and filtering.+Industry-standard dual operational amplifier in a SOIC-8 package. Two independent op-amps share the V+/V- rails and run from a wide 3-30 V single or split supply, with a common-mode input range that includes ground for direct single-supply sensing near 0 V. Gain-bandwidth is 0.7-1.2 MHz and outputs are class-AB, short-circuit protected. A default choice for signal conditioning, active filters, and sensor front-ends.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT1 | output | Output of amplifier 1. Class-AB output stage; can source ~20–30 mA and sink ~10–20 mA; short-circuit protected. Swings from V− up to within ~1.5 V of V+ (Vs=15V, RL=2kΩ). |+| 2 | IN1- | input | Inverting (negative) input of amplifier 1. High-impedance input (Zid ≈ 10 MΩ). Input bias current typ. −20 nA (max −250 nA for LM358). Differential input voltage range ±32 V. |+| 3 | IN1+ | input | Non-inverting (positive) input of amplifier 1. Common-mode input range includes V− (ground) up to (V+)−1.5 V, enabling direct single-supply ground sensing. |+| 4 | V- | power_in | Negative (lowest) supply rail, or ground for single-supply operation. Total supply Vs = (V+)−(V−) = 3 V to 30 V (LM358/A) or 3 V to 36 V (LM358B/BA). Common ground reference for both amplifiers. |+| 5 | IN2+ | input | Non-inverting (positive) input of amplifier 2. Common-mode range V− to (V+)−1.5 V; input bias current typ. −20 nA. |+| 6 | IN2- | input | Inverting (negative) input of amplifier 2. High-impedance input, Zid ≈ 10 MΩ. Differential input voltage range ±32 V. |+| 7 | OUT2 | output | Output of amplifier 2. Class-AB output; source ~20–30 mA, sink ~10–20 mA; short-circuit protected; swings to within ~1.5 V of V+ and to ~5–20 mV of V− with light load. |+| 8 | V+ | power_in | Positive (highest) supply rail. Vs = 3 V to 30 V (LM358/A) or 3 V to 36 V (LM358B/BA). Quiescent current typ. 300–350 µA per amplifier (600–800 µA total). Bypass with 100 nF to V−. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Dual operational amplifier |+| Supply voltage (Vs) | 3-30 V (single or split) |+| Gain-bandwidth product | 0.7-1.2 MHz |+| Common-mode input range | Includes V- (ground) |+| Output drive | Source 20-30 mA, sink 10-20 mA |+| Quiescent current | 300-350 µA per amplifier |+| Channels | 2 independent |+| Package | SOIC-8 |+| Body (L×W×H) | 4.9 × 3.9 × 1.75 mm |++## Ordering variants++- `LM358D (SOIC-8, tube)`+- `LM358DR (SOIC-8, tape & reel)`++## CAD (KiCad official)++- Symbol: `Amplifier_Operational:LM358`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/lm358.pdf) (68 pp, sha256 `ef646b009b0524a8`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude) — every pin and dimension is cited to a datasheet page; refuses to fabricate.+- **CAD:** KiCad official libraries (CC-BY-SA 4.0).++[Datasheet PDF](docs/lm358-datasheet.pdf)
