Abstract
A voltage sensing device with which high-precision voltage sensing is possible without acquiring a unique correction constant for each device. A pair of voltage input nodes NCk and NCk-are selected from n+1 voltage input nodes NC-NCn in switch part, and the selected voltage input nodes NCk and NCk-are connected to inspection input nodes NA and NB. Here, voltage input nodes NCk and NCk-and inspection input nodes NA and NB are connected in two types of patterns of different polarity (forward connection, reverse connection) under the control of control part, and digital data Sfor the two sensed voltage signals Sgenerated in the two types of connection patterns is input to sensed data processing part. With sensed data processing part, sensed voltage data Sthat represents the potential difference between voltage input nodes NCk and NCk-is generated according to the difference in the two sensed voltage signals S
