Abstract
By providing data to a selection switch via a multiplexor so it can be programmed to supply either a current programmably controlled by a shift register or a current fixed by a fused resistor. Selected signals coupled to the multiplexor control the selection of either the resistor or the shift register thus, providing an improved current selection device which is capable of automatically selecting and programming the current supplied to circuits such as digital to analog converters.
