Abstract:
A successive approximation register, SAR, analog-to-digital converter, ADC, ( 400 ) is described. The SAR ADC ( 400 ) includes: an analog input signal ( 410 ); an ADC core ( 414 ) configured to receive the analog input signal ( 410 ) and comprising: a digital to analog converter, DAC ( 430 ) located in a feedback path; and a SAR controller ( 418 ) configured to control an operation of the DAC ( 430 ), wherein the DAC ( 430 ) comprises a number of DAC cells, arranged to convert a digital code from the SAR controller ( 418 ) to an analog form; a digital signal reconstruction circuit ( 450 ) configured to convert the digital codes from the SAR controller ( 418 ) to a binary form; and an output coupled to the digital signal reconstruction circuit ( 450 ) and configured to provide a digital data output ( 460 ). The DAC ( 430 ) is configurable to support at least two mapping modes, including a small signal mapping mode of operation; and the SAR controller ( 418 ) is configured to identify when the received analog signal is a small signal level, and in response thereto re-configure the DAC ( 430 ) and the digital signal reconstruction circuit ( 450 ) to implement a small signal mapping mode of operation.

Claim (Index 5):
The SAR ADC of  claim 4  wherein the SAR controller is configured to adaptively set one or more threshold(s) applied by the signal level range detector circuit to influence when the small signal mapping mode of operation is adopted by the DAC and the digital signal reconstruction circuit.
