General Description

The AS621x IC is a high accuracy digital temperature sensor system that communicates via a 2-wire

digital bus with other devices. It consists of a Si bandgap temperature sensor, an ADC and a digital

signal processor.

The family consists of 3 different variants (AS6212, AS6214 and AS6218). The difference between

these variants is the temperature accuracy:

Temperature Accuracy

Remark

AS6212

±0.2°C

Between -10°C to 65°C

AS6214

±0.4°C

Between 0°C to 65°C

AS6218

±0.8°C

Between 0°C to 65°C

The high temperature accuracy and an ultra-low power consumption (low operation and quiescent

current) makes the AS621x ideally suited for mobile/battery powered applications.

The AS621x is an easy to integrate and use solution, featuring a factory-calibrated sensor, integrated

linearization and the possibility to use 8 different I²C addresses, enabling to use eight AS621x devices

on one bus.

Additionally the AS621x temperature sensor system features an alert functionality, which triggers e.g.

an interrupt to protect devices from excessive temperatures.

The AS621x production test setup is calibrated according NIST and the verification equipment is

calibrated by an ISO/IEC-17025 accredited laboratory
