A capacitor array for a companded pulse code modulation voice codec includes a first plurality of capacitors having a common capacitance C each. A plurality of switching means individually and selectively couple one plate of each of the capacitors to a first point of reference potential or to a second point of reference potential. A second plurality of capacitors has a common capacitance 2C, each, which is coupled in series to form a plurality of junctions, each of the junctions being coupled to a separate one of second plates of the first plurality of capacitors.
