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 | OUT1 | output | Output of amplifier A (channel 1). Output voltage swings to within ~10mV of each supply rail into RL=50kΩ. Short-circuit current ±20mA typical. |+| 2 | -IN1 | input | Inverting input of amplifier A. Voltage range from -Vs -0.3V to +Vs +0.3V. Input bias current 1pA typical (10pA max). |+| 3 | +IN1 | input | Non-inverting input of amplifier A. Rail-to-rail input, common-mode range -0.1V to +Vs +0.1V (VS = 5.5V). Same voltage range as -IN1. |+| 4 | -Vs | power_in | Negative power supply or ground. If not connected to ground, bypass with a 0.1μF capacitor as close to the part as possible. Total supply +Vs to -Vs range 1.4V to 5.5V. |+| 5 | +IN2 | input | Non-inverting input of amplifier B. Rail-to-rail input, common-mode range -0.1V to +Vs +0.1V. |+| 6 | -IN2 | input | Inverting input of amplifier B. Voltage range from -Vs -0.3V to +Vs +0.3V. Input bias current 1pA typical. |+| 7 | OUT2 | output | Output of amplifier B (channel 2). Rail-to-rail output, swings within 10mV of each supply rail. Short-circuit current ±20mA typical. |+| 8 | +Vs | power_in | Positive power supply, 1.4V to 5.5V range (6.0V absolute max +Vs to -Vs). Bypass with a 0.1μF ceramic capacitor close to the pin; a 2.2μF tantalum can be added for better performance. Quiescent current 500nA per amplifier. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `COS6042SRSR`+- `COS6042SRMR`++## CAD (KiCad official)++- Symbol: `COS6042SR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [COSINE datasheet](docs/cos6042sr-datasheet.pdf) (10 pp, sha256 `c1ab67cd8e47b113`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
