Description

The TMP75AIDR is a digital temperature sensor that converts thermal measurements into a digital signal via an integrated analog-to-digital converter (ADC). It communicates using a standard I2C serial interface, allowing for easy integration with microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi. The sensor features programmable resolution and alert function for system monitoring.

Designed for reliability, the IC operates across a broad industrial temperature range from -55°C to +125°C. Its low-voltage operation down to 1.4V makes it suitable for portable and low-power devices, while the SOP-8 package ensures a compact footprint on PCBs.

Frequently Asked Questions

What is the communication interface for the TMP75AIDR sensor?

The TMP75AIDR uses a standard I2C (2-wire serial) interface for communication. This allows it to connect directly to the I2C bus of microcontrollers like Arduino, Raspberry Pi, ESP32, and STM32, requiring only two data lines (SDA and SCL) for bidirectional communication and configuration.

What is the operating voltage range of this temperature sensor IC?

The sensor supports a wide supply voltage range from 1.4V to 5.5V. This makes it compatible with both 3.3V and 5V logic systems, and suitable for low-power, battery-operated devices where the voltage may drop over time.

Can the TMP75AIDR be used in industrial environments?

Yes, the TMP75AIDR is rated for an extended operating temperature range of -55°C to +125°C, qualifying it for industrial applications. Its digital output is robust against noise, and the IC is designed for long-term stability in harsh environmental conditions.

Does this sensor have a programmable alert function?

Yes, it features a programmable temperature alert with an open-drain output (the ALERT pin). You can set upper and lower temperature limits via the I2C interface. When the measured temperature exceeds these limits, the ALERT pin activates, which can be used to trigger a microcontroller interrupt.

Is the TMP75AIDR a surface-mount component?

Yes, the TMP75AIDR comes in an SOP-8 (Small Outline Package) surface-mount package. It is designed for automated PCB assembly and requires appropriate SMD soldering techniques. The compact footprint is ideal for space-constrained circuit board designs.
