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 | SDA | bidirectional | Serial data pin for the SMBus/I2C interface. Open-drain output; requires an external pull-up resistor (5 kΩ recommended, pin current must not exceed 3 mA). |+| 2 | SCL | input | Serial clock pin for the SMBus/I2C interface. Open-drain; requires an external pull-up resistor (5 kΩ recommended). Supports fast mode up to 400 kHz and high-speed mode up to 2.75 MHz. |+| 3 | ALERT | output | Overtemperature alert output. Open-drain; requires an external pull-up resistor. Polarity is programmable via the POL bit (active-low by default); operates in comparator or interrupt mode as configured by the TM bit. |+| 4 | GND | power_in | Ground reference pin for the device. |+| 5 | A2 | input | I2C slave address select input, bit 2. Tie to V+ or GND to set one of eight possible 7-bit slave addresses (1001xxx). |+| 6 | A1 | input | I2C slave address select input, bit 1. Tie to V+ or GND to set the slave address. |+| 7 | A0 | input | I2C slave address select input, bit 0. Tie to V+ or GND to set the slave address. |+| 8 | V+ | power_in | Positive supply voltage input. Operating range 1.4 V to 5.5 V per pin description (recommended supply 3.0 V to 5.5 V per datasheet front page). Decouple with a 0.01 μF bypass capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Tudi |+| Package | MSOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `ADT75ARMZ-REEL-TUDI`+- `ADT75ARMZ-REEL-TUDIADT75BRMZ-REEL-TUDI`+- `ADT75ARMZ-REEL-TUDIADT75ARZ-REEL-TUDI`++## CAD (KiCad official)++- Symbol: `ADT75ARMZ-REEL-TUDI`+- 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:** [Tudi datasheet](docs/adt75armz-reel-tudi-datasheet.pdf) (None pp, sha256 `741b5191d35ac0d5`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
