An analog-to-digital converter system for sampling an input signal includes at least one offset channel. Each channel includes a differential amplifier with a signal input coupled to the input signal, an offset input for receiving an offset signal and an amplified difference output, an analog-to-digital converter having a signal input coupled to the amplified difference output and having a signal output, and an offset index signal source coupled to the differential amplifier offset input. The system further includes an offset controller having at least one output coupled to a corresponding at least one offset index signal source and at least one input coupled to a corresponding at least one analog-to-digital converter signal output. The system also includes a signal constructor having at least one input coupled to a corresponding at least one analog-to-digital converter signal output and operable to provide a relatively high resolution digital output signal.
