Introduction –
Temperature Sensor ICs
ABLIC’s temperature sensor ICs offers digital output temperature sensor ICs that output a digital signal corresponding to the temperature, analog output temperature sensor ICs that output an analog voltage corresponding to the temperature, and temperature switch ICs (thermostat ICs) that output a H/L signal corresponding to the temperature.
We support the temperature monitoring and control of equipment with an extensive lineup of products featuring high accuracy, ultra-low current consumption and high temperature operation.
