The disclosure includes an analog to digital converter (ADC) comprising a successive approximation register (SAR) unit including a capacitive network to take a sample of an analog signal and a comparator to approximate a digital value based on the analog signal sample via successive comparison. The disclosure also includes a programmable sequencer. The sequencer includes a control memory containing control signal states indicating control signals to operate the SAR unit. The sequencer also includes a program memory including sequence instructions defining a duty cycle for the SAR unit by referencing the control signal states in the control memory. The sequencer also includes a processing circuit to apply control signals according to the control signal states in an order defined by the sequence instructions to manage a sequence of operations at the SAR unit according to the duty cycle to control the ADC.
