Provided is a method for performing analog to digital conversion of a plurality of analog signal channels. The method may comprise successively processing each analog signal channel of a plurality of analog signal channels. The processing of an analog signal channel of the plurality of analog signal channels may comprise: selecting the analog signal channel from the plurality of analog signal channels, generating an analog output signal corresponding to an analog input signal transmitted over the selected analog signal channel, and sampling the analog output signal using a successive approximation register (SAR) converter. Sampling the analog output signal using a SAR converter may comprise sampling the analog output signal a specific number of times to produce a respective plurality of digital samples corresponding to the selected analog input signal.
