The purpose of the invention is to accurately operate a circuit using a simple configuration. This electronic apparatus is provided with a first reference voltage generation circuit, a second reference voltage generation circuit the power consumption of which is lower than that of the first reference voltage generation circuit, two logic circuits, and a reference voltage switching unit. The two logic circuits input and output to each other a logic value referenced to a reference voltage . The reference voltage switching unit supplies, in a normal mode in which both of the two logic circuits are operating, the reference voltage from the first reference voltage generation circuit to the two logic circuits; and supplies, in a power-saving mode in which one of the two logic circuits is operating, the reference voltage from the second reference voltage generation circuit to the one operating logic circuit. |
