Abstract
An analog to digital converter has an analog signal input, reference voltage divider and a plurality of comparators. Each comparator has a first input connected to said analog signal input and a reference input connected to receive a respective predetermined reference voltage from the reference voltage divider. In addition, test mode circuitry is provided for feeding a sequence of test voltages from the voltage divider to the first input of the comparators in a test mode. A decoder is connected to an output of each comparator for generating a binary output signal representative of an input analog signal.
