High precision and low power consumption digital temperature sensor chip with single wire interface—JHM3011
JHM3011 is a high-precision and low -power digital temperature sensor chip with a single line interface.
JHM3011 is a high-resolution digital temperature sensor IC that communicates via a single-wire serial digital data output with other devices. It consists of a temperature sensor, an ADC and a digital signal processing unit. It features high temperature accuracy (±0.5℃ between -40℃ to 150℃) and high resolution (down to 0.0625℃). It can operate within the supply voltage of 2.7V to 5.5V with a typical average current 0.5mA.
JHM3011 is an easy to integrate and use solution, featuring a factory calibrated sensor, integrated linearization, ideal for PT100 RTD replacement. The devices are available in 6-pin DFN footprint.
