Abstract
A converter circuit provides analog to digital and digital to analog functions on a single silicon device. A flash analog to digital converter produces digital outputs using comparators which each receive an input signal and which each have different reference voltages. A decoder receiving digital inputs activates switches to connect selected ones of the same voltage references used by the flash analog to digital converter to a buffer which produces an analog output. The converter circuit can be a single or multi-stage flash analog to digital converter operating in a single channel or multi-channel environment. Timing and control logic prevents switching from occurring at times when perturbations on the voltage references could affect the analog and digital outputs.
