A programmable mixed-mode circuit (180) has both digital (215,217) and analog (120,120',120") circuit portions. The digital portion (215,217) is provided by programmable digital logic. The analog portion (120,120',120") has a variety of analog circuits, including voltage references (218), high-speed comparators (208,209) and circuits (80) that are selectively configurable to provide operational amplifier or comparator functions. The analog circuits (122-125) are interconnected by programmable switch elements (128-131,160-167) so that the connection of the analog circuits to one another, to input or output pins (A0-A3,B0-B3,C0-C3) and to the digital circuitry (215,217) can be programmed.
