A driver circuit which drives a signal line includes a first output section for outputting a reference voltage potential to the signal line during a first period and a second output section for outputting one of a first information voltage potential and a second information voltage potential in accordance with an input signal during a second period.

Signal transmission driver circuit, receiver circuit, and method thereof

A plurality of different reference voltages are generated. A set of differential conversion circuits has first input terminals subjected in common to an analog input signal and second input terminals subjected to the respective reference voltages, and converts differences between voltages at the first and second input terminals into differential output voltages. A first A/D conversion circuit compares the analog input signal with the reference voltages to perform a higher-order A/D conversion of the input analog signal. At least two of the differential output voltages are selected. An interval between the selected differential output voltages is divided, and divided voltages are generated in accordance with the division. A second A/D conversion circuit compares the divided voltages to perform a lower-order A/D conversion of the analog input signal.
