Ultra-low power and cost effective MS1088 temperature sensor
Microdul's designers have developed a silicon based temperature sensor that reaches the accuracy of +/-0.3°C from 0°C to 45°C based on a single point compensation scheme. The typical operating current is less than 25µA. The chip has a digital interface (I2C) and is as QFN16 package available.
