ams OSRAM AS6204 IC Digital Temperature Sensor

ams OSRAM AS6204 IC Digital Temperature Sensor targets consumer applications such as laptops, cameras, and tablets. The board-mount sensor communicates via a 2-wire digital bus with other devices. The AS6204 IC Digital Temperature Sensor also consists of a Si-bandgap temperature sensor, an analog-to-digital converter, and a digital signal processor. The factory-calibrated sensor features ultra-low power consumption (low operation and quiescent current) and integrated linearization. The sensor's additional I2C addresses make it ideal for the prototyping phase of a product, where several heat-sensitive areas might need monitoring.


  • Complete sensor system with serial bus connection
  • Full-digital system with four I2C addresses
  • 1.8V to 3.6V supply voltage range
  • High measurement accuracy
    • ±0.4°C (0 to +65°C)
    • ±1°C remaining operating temperature span
  • Alert functionality for exact temperature control
  • 12-bit resolution
  • 24ms to 40ms conversion time range
  • Low power consumption
    • 6µA at operation (typical, at 4Hz)
    • 0.1µA at standby (typical)
  • -40°C to +125°C operating temperature range
  • Moisture Sensitivity Level (MSL) 1
  • Small 1.5mm x 1mm WLCSP package) PCB footprint


  • Tablets
  • Convertibles
  • Laptops
  • Personal computers
