The converter has a three decision range conversion algorithm using ternary values. The converter has a single unipolar reference voltage source (Vr) and computing method (MC) to establish a voltage value. The voltage value is determined by determining a sum value from the voltage calculated during the previous iteration, and a value which is the product of the ternary value during the preceding iteration and the reference voltage. Computing is by switched capacitors (Cr, C1, C2) connected to a single operational amplifier (11). This provides a more compact circuit with less surface integration having a smaller current requirement whilst having a good conversion quality for applications such as hearing aids.
