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 | VCC | power_in | Positive supply voltage input, 2.7V to 5.5V. Bypass to GND with 1uF ceramic (and optionally a 10uF tantalum in parallel) placed close to the pin. |+| 2 | REF+ | input | Positive reference input. Absolute/common-mode voltage range 0.1V to VCC. Differential reference VREF = REF+ - REF- must be within 0.1V to VCC. |+| 3 | REF- | input | Negative reference input. Absolute/common-mode voltage range GND to (VCC - 0.1V). Sets the low reference rail for the differential VREF used by the delta-sigma converter. |+| 4 | IN+ | input | Positive differential analog input. Absolute range (GND - 0.3V) to (VCC + 0.3V); differential input range VIN = IN+ - IN- is -VREF/2 to +VREF/2. Sampling capacitance ~6pF. |+| 5 | IN- | input | Negative differential analog input. Absolute range (GND - 0.3V) to (VCC + 0.3V); pairs with IN+ to form the fully differential input. Sampling capacitance ~6pF. |+| 6 | GND | power_in | Device ground. Provide a low-impedance return path; all voltages in the datasheet are referenced to this pin. |+| 7 | CS | input | Active-low chip select / conversion control input. CS low enables SDO and initiates data output; CS high tri-states SDO and (with FO tied to GND or VCC) puts the part into Sleep Mode. VIH >= 2.5V (VCC >= 2.7V), VIL <= 0.6V. |+| 8 | SDO | tri_state | Three-state serial data output. Drives the 32-bit conversion result MSB-first, clocked out on SCK falling edges. High-Z when CS is high; VOH >= VCC - 0.5V at -800uA, VOL <= 0.4V at 1.6mA. |+| 9 | SCK | bidirectional | Bidirectional serial clock for the SPI/MICROWIRE data output interface. Configured as an input in external-SCK mode (up to 2MHz) or as a push-pull output in internal-SCK mode (~19.2kHz on LTC2411, ~17.5kHz on LTC2411-1). Mode is selected automatically by the state of SCK when CS falls. |+| 10 | FO | input | Frequency / notch-filter select and external oscillator input. On LTC2411: FO = GND selects internal oscillator with 60Hz notch, FO = VCC selects 50Hz notch, or drive with an external 2.56kHz-500kHz clock to set the user-defined notch. On LTC2411-1: FO = GND or VCC selects simultaneous 50/60Hz rejection with the internal oscillator; external clock override is also supported. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | MSOP-10 |+| Category | Data Acquisition |+| Pins | 10 |++## Ordering variants++Same part, different packaging or reel option.++- `LTC2411CMS#PBF`+- `LTC2411CMS#TRPBF`+- `LTC2411CMS#TRPBFIMS#PBF`+- `LTC2411CMS#TRPBFIMS#TRPBF`+- `LTC2411CMS#TRPBF-1CMS#PBF`+- `LTC2411CMS#TRPBF-1CMS#TRPBF`+- `LTC2411CMS#TRPBF-1IMS#PBF`+- `LTC2411CMS#TRPBF-1IMS#TRPBF`++## CAD (KiCad official)++- Symbol: `LTC2411CMS#TRPBF`+- Footprint: `Package_SO:MSOP-10_3x3mm_P0.5mm`+- 3D model: MSOP-10 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588885698287423488) (42 pp, sha256 `a40f75661e44ecab`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
