| 摘要 | PURPOSE:To attain the selection of A/D and D/A conversion by providing a conversion mode switching means and an analog lead-out means to a D/A converting circuit being a component of an A/D converting circuit. CONSTITUTION:The conversion mode switching means 8 and the lead-out means 6, 7 extracting an analog output signal are added to the A/D converting circuit functioning the D/A converting circuit 5 as a component. In operating this signal converter as the D/A converting circuit 5, a signal is converted to an analog signal and extracted from the terminal 7 by controlling a control logic circuit 3 by the conversion mode switching means 8, releasing the closed loop and giving a digital input signal to be converted to an output terminal 4. | ||||||
