Description

The TMP423BIDCNR from Texas Instruments is a precision digital temperature sensor that converts thermal measurements into a digital signal via an integrated analog-to-digital converter (ADC). Its core sensing element and signal conditioning circuitry are designed for stability and minimal drift over time and temperature variations.

Operating from a 2.7V to 5.5V supply, it is compatible with both 3.3V and 5V logic systems. The sensor communicates over a standard I2C bus, allowing for daisy-chaining and simple connection to most microcontrollers and single-board computers. Its small SOT-23-8 footprint makes it ideal for space-constrained PCB designs requiring reliable temperature monitoring.

Key Features

  • High Precision Measurement: Delivers typical accuracy of ±1°C for reliable thermal management.
  • Broad Operating Voltage: Supports 2.7V to 5.5V DC, ensuring compatibility with diverse system power rails.
  • Optimized Power Profile: Features low quiescent current, making it suitable for portable and power-sensitive devices.
  • Standard Digital Interface: Utilizes a 2-wire I2C/SMBus protocol for simplified system integration and multi-device networks.
  • Robust Miniature Package: Housed in an industry-standard SOT-23-8 (SOT23-8) surface-mount package for dense PCB layouts.
  • Extended Temperature Range: Engineered for stable operation across a wide ambient temperature range.

Applications

  • Thermal monitoring and protection in embedded computing systems (e.g., Raspberry Pi, Arduino shields).
  • Environmental sensing in portable consumer electronics and IoT devices.
  • Temperature compensation and logging in precision measurement equipment.
  • System health monitoring in telecom, networking, and industrial control hardware.
  • Battery temperature management in power tools and energy storage systems.
