A multiplying digital to analog converter providing a sequence of signal samples in which each sample represents the product of a respective sample of an analog input signal and a respective binary number is disclosed. The converter comprises a semiconductor device including a plurality of charge storage cells each paired with a respective digit of a binary number. The quantity of charge introduced into each of the storage regions is dependent on the sample of the analog signal and the presence of a "1" in the respective digit of the binary number. The product of the sample of the analog signal and the binary number is obtained by combining the charges so introduced into the storage regions.
