General Description

The AS6204 IC is a high accuracy 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.

It has a very high temperature accuracy (±0.2 °C between -10 °C to 20 °C) and an ultra-low power

consumption (low operation and quiescent current) which makes it ideally suited for mobile/battery

powered applications.

The AS6204 is an easy to integrate and use solution, featuring a factory calibrated sensor, integrated

linearization and the possibility to use 2 different I²C addresses, enabling to use two AS6204 devices

on one bus.

Additionally the AS6204 temperature sensor system also features an alert functionality, which triggers

e.g. an interrupt to protect devices from excessive temperatures.
