A converter may include an input terminal to receive a first analog signal, a digital-to-analog converter to provide second analog signals related to digital values applied to the digital-to-analog converter, a comparator to receive the first and second analog signals, the comparator comprising a variable gain amplifier to provide an output signal based on a difference between the first and second analog signals, a state machine to receive the output signal of the comparator and generating the digital values applied to the digital-to-analog converter based on the output signal of the comparator, and a controller to selectively set the gain of the variable gain amplifier.
