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. The output voltage range extends to within millivolts of each supply rail (typ. 10 mV with RL=10 kΩ). |+| 2 | -IN1 | input | Inverting input of amplifier A. Voltage range: -Vs -0.3 V to +Vs +0.3 V. Input terminals are diode-clamped to the supply rails; limit input current to 10 mA if signals swing beyond the rails. |+| 3 | +IN1 | input | Non-inverting input of amplifier A. Same voltage range as -IN1 (-Vs -0.3 V to +Vs +0.3 V). Rail-to-rail input capability with common-mode range from -0.1 V to 5.6 V (Vs=5 V). |+| 4 | -Vs | power_in | Negative power supply or ground. If not tied to ground, bypass with a 0.1 µF capacitor placed as close to the pin as possible. Supports single-supply (0 V) or dual-supply (±1.25 V to ±2.25 V) operation. |+| 5 | +IN2 | input | Non-inverting input of amplifier B. Same voltage range as -IN2 (-Vs -0.3 V to +Vs +0.3 V). Rail-to-rail input. |+| 6 | -IN2 | input | Inverting input of amplifier B. Voltage range: -Vs -0.3 V to +Vs +0.3 V. Input terminals are diode-clamped to the supply rails. |+| 7 | OUT2 | output | Output of amplifier B. Rail-to-rail output; short-circuit sourcing 100 mA, sinking 120 mA (typ.). |+| 8 | +Vs | power_in | Positive power supply, 2.5 V to 5.5 V (single-supply) or +1.25 V to +2.25 V (dual-supply). Bypass with a 0.1 µF ceramic capacitor placed as close to the pin as possible; a 2.2 µF tantalum can be added for better performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | COSINE |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `COS8052MR`+- `COS8052MRSR`++## CAD (KiCad official)++- Symbol: `COS8052MR`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [COSINE datasheet](docs/cos8052mr-datasheet.pdf) (10 pp, sha256 `38c120e198112d0a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
