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 | IN- | input | Inverting analog input. Connect to the load side of the external shunt (sense) resistor. Common-mode range −6 V to 80 V; differential (V_IN+ − V_IN−) up to ±80 V for 1 s. |+| 2 | GND | power_in | Device ground reference. |+| 3 | REF2 | input | Reference 2 analog input. Connect between 0 V and VS. Together with REF1 sets the output-reference (zero-current) voltage via internal 50 kΩ dividers, enabling bidirectional current sensing. |+| 4 | NC | unconnected | Reserved. Connect to ground or leave floating. |+| 5 | OUT | output | Analog output voltage. V_OUT = Gain × (V_IN+ − V_IN−) + V_REF, where Gain = 20 V/V for CSA240L. Swings from V_GND+1 mV up to VS−15 mV with a 10 kΩ load; drives up to 2 nF without sustained oscillation. |+| 6 | VS | power_in | Positive power supply, 2.7 V to 5.5 V (absolute max 6 V). Typical quiescent current 1.4 mA. |+| 7 | REF1 | input | Reference 1 analog input. Connect between 0 V and VS. Together with REF2 sets the output-reference (zero-current) voltage via internal 50 kΩ dividers. |+| 8 | IN+ | input | Non-inverting analog input. Connect to the supply side of the external shunt (sense) resistor. Common-mode range −6 V to 80 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | analogysemi |+| Package | SOIC-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `CSA240LCSOIC8`+- `CSA240LCSOIC8CSA240MCSOIC8`+- `CSA240LCSOIC8CSA240NCSOIC8`+- `CSA240LCSOIC8CSA240LCMSOP8`+- `CSA240LCSOIC8CSA240MCMSOP8`+- `CSA240LCSOIC8CSA240NCMSOP8`+- `CSA240LCSOIC8CSA240LCTSSOP8`+- `CSA240LCSOIC8CSA240MCTSSOP8`+- `CSA240LCSOIC8CSA240NCTSSOP8`++## CAD (KiCad official)++- Symbol: `CSA240LCSOIC8`+- 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:** [analogysemi datasheet](docs/csa240lcsoic8-datasheet.pdf) (24 pp, sha256 `520b4237ad8a16cf`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
