Analog-to-digital converter, system-on-chip and electronic control system

An analog-to-digital converter (ADC), comprising:

• a sequence management circuit, which is configured to, after the ADC is triggered and activated, load a target sequence count for a streaming access mode and generate a multi-channel input control signal and a sequence selection output control signal, the sequence management circuit is further configured to generate a stream interrupt signal when an actual sequence count kept in the ADC reaches the target sequence count;
• a multi-channel input multiplexer, which is coupled to the sequence management circuit and is configured to receive an analog signal to be converted and, under the control of the multi-channel input control signal, sequentially strobe associated input channel(s) according to a designated conversion priority order designated by each sequence, thereby generating a sample sequence;
• an analog-to-digital conversion (ADC) circuit, which is coupled to the multi-channel input multiplexer and is configured to convert the sample sequence into a corresponding digital sequence;
• a sequence output multiplexer, which is coupled to the ADC circuit and a sequence data register and is configured to store the digital sequence output from the ADC circuit into the sequence data register according to a specified sequence sorting scheme under the control of the sequence selection output control signal;
• and
• an interrupt generation circuit, which is coupled to the sequence management circuit and an associated interrupt controller and is configured to notify the interrupt controller to perform an interrupt processing on the ADC when the stream interrupt signal is valid.
