A system including a sensing system, a first chopped circuit, a second chopped circuit, and a clock generator. The sensing system is configured to provide sensed input signals. The first chopped circuit is configured to provide a switched output signal that switches in response to values of the sensed input signals crossing a limit. The second chopped circuit is configured to provide a high resolution output signal that corresponds to the sensed input signals and has a higher resolution than the switched output signal. The clock generator is configured to provide clock signals that synchronize chopping of the first chopped circuit and the second chopped circuit.
