ABSTRACT:
A circuit that includes at least two driver circuits. Each driver circuit receives analog information and drives a value related to the analog information to an analog bus. Each driver circuit also includes a select transistor to pass the value related to the analog information to the analog bus when the driver circuit is selected. The select transistor includes a source and a bulk. Each driver circuit further includes a bulk potential control circuit (BPCC) to couple the bulk to the source when the driver circuit is selected and to couple the bulk to a voltage supply when the driver circuit is not selected.
