A switching circuit and a method for providing a switch array having an on resistance is presented. The switch array has a plurality of switches, where each switch is arranged to be in different configuration states. The states include an enabled configuration and a disabled configuration. The switching states include an on state and an off state. Each switch is held in the off state when in the disabled configuration. Control circuitry sets the switches to either the enabled configuration or the disabled configuration, and a memory element coupled to the control circuitry and arranged to store configuration data for setting the configuration state of each of the switches. The control circuitry sets the configuration state of the switches based on a signal received from the memory element. The on resistance of the switch array depends on the switching state of the switches and their individual on resistances.
