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 | ADDR | input | I2C bus slave address selector. Tie LOW for slave address 0101001b or HIGH for 0111001b. V_IH >= 0.7*VCC, V_IL <= 0.3*VCC. |+| 2 | VCC | power_in | Positive supply voltage input, 2.3 V to 3.6 V (2.5 V typ). Place a 0.1 uF bypass capacitor as close as possible to the IC. |+| 3 | GND | power_in | Ground reference (0 V) for the IC. |+| 4 | TEST | input | Factory test pin. Must be connected to GND in normal operation. |+| 5 | SCL | input | I2C bus serial clock input. Open-drain line requiring an external pull-up resistor. Supports up to 400 kHz (fast mode). V_IH >= 1.26 V, V_IL <= 0.54 V. |+| 6 | SDA | bidirectional | I2C bus serial data line. Open-drain bidirectional line requiring an external pull-up resistor. V_OL <= 0.4 V at I_OL = 3 mA. |+| 7 | INT | output | Interrupt output (active low, open-drain). Asserted when ADC result crosses the programmed TH_LOW/TH_HIGH thresholds with persistence. V_OL <= 0.4 V at I_OL = 3 mA. Requires external pull-up. |+| 8 | NC | unconnected | No internal connection. Leave floating or tie to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ROHM |+| Package | WSON-8-EP(2x2) |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `BH1726NUC-E2`++## CAD (KiCad official)++- Symbol: `BH1726NUC-E2`+- Footprint: `Package_SON:WSON-8-1EP_2x2mm_P0.5mm_EP0.9x1.6mm`+- 3D model: WSON-8-EP(2x2) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ROHM datasheet](docs/bh1726nuc-e2-datasheet.pdf) (19 pp, sha256 `652d45f11a194522`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
