<p>In an electronic conversion circuit for converting an analog value to digital codes or digital codes to an analog value, the circuit comprises at least two analog processing units (11A, 11B) providing conversion hold blocks. Each of the analog processing units (11A, 11B) has two functions, that is, one function is to perform sampling of an analog value and to circularly convert the analog value to an output analog value in order to obtain a digital value based on the output analog value by a cyclic A/D conversion method, and the other function is to sequentially input digital codes and to convert digital codes in order to obtain an analog value.</p> |
