Electronic circuit with digital-to-analog converter

The embodiment of the invention relates to an electronic circuit with a digital-to-analog converter. The electronic circuit includes a first channel and a second channel that receive a first analog signal and a second analog signal, respectively. The first channel includes a first digital-to-analog converter having an output coupled to the first input of the first symbol comparator, and the second channel includes a second digital-to-analog converter. Upon receiving a self-test mode signal signaling the test phase, the switching network selectively couples the output of the second digital-to-analog converter to the second input of the first symbol comparator. The ramp generation circuit provides two identical ramps of the digital code to the first digital-to-analog converter and the second digital-to-analog converter, the two identical ramps being shifted with a programmable offset relative to each other. The check circuit issues a test state signal based on an output of the first symbol comparator. 本公开的各实施例涉
