JHM3012 is a low-power high-resolution digital temperature sensor IC that communicates via I2C interface. It consists of a temperature sensor, an ADC and a digital signal processing unit. It features high temperature accuracy (±0.2℃ between 0℃ to 50℃) and high resolution (down to 0.003℃). It can operate within the supply voltage of 1.8V to 3.6V with a typical average current 4.7μA.

JHM3012 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.
