ams OSRAM AG AS621x Ultra-Low power digital temperature sensor family

The AS621x is the second generation of the digital temperature sensor family, designed for high accuracy applications with ultra-low power consumption. The new digital sensor design offers eight I²C addresses and a supply voltage from 1.71 V to 3.6 V. The AS621x family is a fully calibrated and linearized sensor system that is easy to integrate into any digital system. It provides a 16-bit resolution over the full temperature range from -40 °C to +125 °C. For power-sensitive applications, the device can enter a low-power wait mode with 0.1 μA current consumption.

Key features

• Ultra-low Power Consumption: 6 μA @ 4 samples/sec (Typ.)
• Small WLCSP Package (1.5 x 1.0 mm)
• High Temperature Accuracy of ±0.2 °C (-10 °C to 65 °C)
• Full-digital System with up to Eight I2C Addresses

Additional features:

• Supply voltage: 1.71 V to 3.6 V
• Operating temperature: -40 °C to 125 °C
• Programmable alert output pin
• Factory calibrated

Additional Benefits:

• Long battery life and low self heating
• 3 different versions (AS6212, AS6214 & AS6218) with different temperature accuracies in order to perfectly match customer requirements.
• "Easy to Use" solution, i.e. no calibration or linearization needed
• Minimal board space and fast reaction time
• 3 different versions (AS6212, AS6214 & AS6218) to optimally meet the accuracy requirements

Applications

• Industrial Automation
• HVAC and Thermostat Control
• High Accuracy Consumer Electronics
• Wearables/Mobile Health
