MICRODUL TEMPERATURE SENSOR FOR HIGHEST ACCURACY
Microdul supplies the MS108X-series of ultra-low-power temperature sensors. For example, the MS1089 has a typical current consumption of 27nA when measuring once per minute, and the typical current between measurements is only 4nA. The sensors are interfaced with I2C or SPI communication and offer a single GPIO handshake mechanism to save additional power and to optimise the timing of the measurement sequence. The MS1088 features a battery end-of-life monitoring function. The temperature sensors are available in small chip scale packages (CSP) and QFN. The chip scale package can be soldered like a normal SMD component.
