Abstract
A combination of a precision analog-to-digital converter (ADC), an analog amplifier having selectable gains and an intelligent controller to coordinate the amplifier gain selection and placement of the digital conversion results into at least one register provide for a very high resolution analog-to-digital conversion process, at a high sample rate and low power consumption. For example, a 14-bit ADC may be used with selectable gain analog amplification, e.g., ×1, ×2, ×4 and ×8, between the sampled signal and ADC input and an intelligent controller to provide a 17-bit conversion number having proper scaling of the digital sample words. The entire high resolution analog-to-digital conversion process may be automatically performed without additional control from external hardware/software.
