Highly accurate temperature sensors

25 November 2019 Analogue, Mixed Signal, LSI

New from ams is the AS621x-generation of temperature sensors delivering optimised performance for consumer electronic devices and wearables, health-related monitoring systems and heating, ventilation and air conditioning (HVAC) systems.

Prototyping and design verification are simplified thanks to the 1,5 mm2 WLCSP’s industry-standard serial interface with eight I2C addresses and a factory-calibrated sensor. The sensors come in three accuracy versions: 0,2°C for the AS6212; ±0,4°C for the AS6214; and 0,8°C for the AS6218.

ams has decreased the supply voltage range to a low level of 1,71 V, and by additionally increasing the number of I2C addresses to eight, customers have the added flexibility to monitor up to 8 hot spots in their systems at minimum effort – especially during prototyping.

The AS621x is a complete digital temperature system, which has been factory-calibrated to an accuracy down to 0,2°C. For greater sensitivity to temperature change, the resolution of the temperature value output has also increased to 16 bits.
