ADT75ARMZ-REEL-TUDI from Tudi, in a MSOP-8. 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. |
