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 | OUTA | output | Output of amplifier A. Rail-to-rail output; swings to within ~10mV of each supply rail (1mV @ 100kΩ, 10mV @ 10kΩ, 40mV @ 2kΩ). Short-circuit current typ. 45mA source / 50mA sink. |+| 2 | -IN1 | input | Inverting (negative) input of amplifier A. Input voltage range from -Vs -0.3V to +Vs - 1V. Input terminals are diode-clamped to the supply rails; signals exceeding rails by >0.5V must be current-limited to 10mA. |+| 3 | +IN1 | input | Non-inverting (positive) input of amplifier A. Same voltage range as the inverting input (-Vs -0.3V to +Vs - 1V). Common-mode range with Vs=5.5V spans -0.1V to 4.5V; CMRR typ. 125dB. |+| 4 | -Vs | power_in | Negative supply / ground pin. For single-supply operation tie to GND; for dual-supply operation connect to negative rail (±1.05V to ±2.75V). Bypass with 0.1µF ceramic close to the pin if not tied directly to ground. |+| 5 | +IN2 | input | Non-inverting (positive) input of amplifier B. Same voltage-range and common-mode specifications as +IN1. |+| 6 | -IN2 | input | Inverting (negative) input of amplifier B. Input voltage range from -Vs -0.3V to +Vs - 1V; diode-clamped to supplies. |+| 7 | OUTB | output | Output of amplifier B. Rail-to-rail; same drive characteristics as OUTA. |+| 8 | +Vs | power_in | Positive supply pin. Operating range 2.1V to 5.5V (single supply) or ±1.05V to ±2.75V (dual). Bypass with a 0.1µF ceramic capacitor placed as close as possible to this pin (2.2µF tantalum optional for improved performance). Total quiescent current ~170µA (85µA per amplifier). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `COS358SRSR`+- `COS358SRMR`++## CAD (KiCad official)++- Symbol: `COS358SR`+- 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:** [COSINE datasheet](docs/cos358sr-datasheet.pdf) (10 pp, sha256 `7499c4d7cd32eb92`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
