Frequently Asked Questions

What is the communication interface for the TMP103AYFFR sensor?

The TMP103AYFFR utilizes a standard I2C (also known as SMBus) digital interface. This allows direct connection to the I2C pins of most microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi without needing an analog-to-digital converter, simplifying wiring and code integration.

What is the operating voltage range for this sensor?

This sensor is designed for low-voltage systems, with a specified supply voltage range from 1.4V to 2.8V. It is compatible with common 1.8V and 2.5V logic levels, making it ideal for battery-powered and portable electronic devices where power efficiency is critical.

How accurate is the TMP103AYFFR, and what is its temperature range?

The sensor operates across a wide industrial temperature range of -40°C to +125°C. For specific accuracy figures (typically within ±0.5°C or ±1°C over certain ranges), please consult the official TMP103 datasheet from UMW, as accuracy can vary based on calibration and operating conditions.

What does the DSBGA-4 package mean for PCB design?

DSBGA-4 stands for Die-Size Ball Grid Array with 4 balls. This is an ultra-compact, leadless surface-mount package measuring only 0.9mm x 0.9mm. It requires careful PCB layout and reflow soldering processes typically used in high-density consumer electronics manufacturing.
