ABSTRACT:
An integrated circuit driver structure, comprising an amplifier, a current mirror block and an external current set resistor, is provided that is digitally configurable to operate in a current output mode or in a voltage output mode with its output level controlled by an external voltage. The current mirror block comprises multiple current sources, all having the same gate bias supplied by the output of amplifier. At any time, at least one current source is connected to supply the reference current to resistor, while all other current sources are connected to mirror the reference current to the load current output towards the load. A current gain ratio is based on the number of current sources connected to supply resistor and the number connected to mirror the reference current.
