ADT75ARMZ-REEL-TUDI

Tudi · Temperature and Humidity Sensor · MSOP-8

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.
