Abstract
Provided is an analog-to-digital converter that includes a first analog-to-digital conversion (ADC) stage connected to input a first analog signal and a second ADC stage connected to input a second analog signal produced by the first ADC stage. A tone detector enables the second ADC stage from a disabled state when a first condition indicating the presence of a high-level interference tone is satisfied and disables the second ADC stage from an enabled state when a second condition indicating the absence of a high-level interference tone is satisfied.
