AMS AG AS621x Ultra-Low power digital temperature sensor family

The AS621x is the second generation of the 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
