Abstract
In one example, an apparatus includes a first switch array including a first plurality of switches. A first resistor array includes a first plurality of resistor pairs, where each resistor pair in the first plurality of resistors is coupled to one switch of the first plurality of switches. The apparatus also includes a second switch array including a second plurality of switches. A second resistor array includes a second plurality of resistor pairs, where each resistor pair in the second plurality of resistors is coupled to one switch of the second plurality of switches. The apparatus further includes a plurality of output nodes configured to transmit an analog voltage, where each output node of the plurality of output nodes is connected to one resistor pair of the first resistor array and one resistor pair of the second resistor array.
