Abstract
This application relates to ADC circuitry. An ADC circuit () has first and second conversion paths () for converting analogue signals to digital and is operable in first and second modes. In the first mode, the first and second conversion paths are connected to respective first and second input nodes () to receive and convert full scale first and second analogue input signals (Ain, Ain) to separate digital outputs (Dout, Dout). In the second mode, the first and second conversion paths are both connected to the first input node (), to convert the first analogue input signal (Ain) to respective first and second digital signals, and the first and second conversion paths are configured for processing different signal levels of the first analogue input signal. A selector () select the first digital signal or the second digital to be output as an output signal based on an indication of amplitude of the first analogue input signal.
