1. A circuit comprising:
- an analog circuit adapted to measure a voltage at two separate input terminals relative to a reference voltage;
a counter; and
a digital controller, coupled to the analog circuit and the counter, the digital controller adapted to control the counter and the analog circuit to define a time period during which the voltage is measured and convert the voltage measured to a digital value.
