This digital-analog converter receives a digital number and applies it to a counter capable of handling an n-bit binary capacity. When the counter counts to its full number, e.g. 1111 for a 4-bit capacity a writing signal generated in a control section causes the complement of the applied number to be written into the counter. The counter is then able to start counting from this complement number to the full (1111) number again. The control section then complements the written-in number back to the original number and counts up to the full number yet again. Thus, if the original binary number is 1100 and the reverse number, the counter counts 1100 and 0011 repetitively. At each count reversal, a flip-flop reverses, and a pulse corresponding in length to the original number is produced within each full count interval and that pulse is filtered by a low-pass filter to produce an analog signal corresponding to the original digital one.
