Abstract

PURPOSE:To obtain a constant output impedance, by connecting two groups of weighted resistances in series to deliver an output from the middle point of the groups and then giving a complementary switching to the switches provided in parallel to each resistance by the digital signal. CONSTITUTION:The weighted resistances R1-R4 plus R1'-R4' are connected in series, and the resistance R0 is connected to R4. Then the other terminals of R0 is connected to R4'. When the digital input D1 is ''1'', the switch S1 is closed with the switch K1 opened. As a result, the resistance R1 is short-circuited. In the same way, the switches S2-S4 plus K2-K4 are controlled by the digital signals D2-D4. Then the analog output corresponding to the digital signal is extracted from the middle point between the resistances R0 and R4'. Thus the output impedance is always 16R when viewed from the output terminal.
