INTERFACE CIRCUIT, PRESSURE SENSOR MODULE EMPLOYING THE SAME AND METHOD FOR TRANSFERING VOLTAGE EMPLOYING THE SAME

摘要

PURPOSE: An interface circuit, a pressure sensor module using the same and a voltage transforming method using the same are provided to obtain power desired by a system by converting an input voltage into an optimized target output voltage for various air conditioner systems. CONSTITUTION: An interface circuit, a pressure sensor module using the same and a voltage transforming method using the same comprises a voltage attenuator(12) and an offset voltage generation part(13). The voltage attenuator attenuates the input voltage. The offset voltage generation part is connected with the voltage attenuator to provide a direct current offset voltage to the output voltage of the voltage attenuator.
