ABSTRACT:
In an embodiment, an analog to digital converter (ADC) has a dynamic power circuit. The ADC has a track-and-hold circuit with an output and a track mode. The ADC also has a comparator with an input. A preamplifier is coupled between the track-and-hold output and the comparator input. At least one of a preamplifier current and a comparator current are limited during the track mode to reduce ADC power consumption.
