Abstract: A circuit includes: first analog-to-digital converters, ADCs (105) configured to be coupled to respective ones of first sensors(101); a first multiplexer, MUX (111) coupled to output terminals of the first ADCs; a second MUX (109) configured to be coupled to second sensors (103) which are redundant sensors for the first sensors; a second ADC (107) coupled to an output terminal of the second MUX, the first MUX and the second MUX being controlled by a selection signal (108); a first checker circuit (133) configured to compare a first data at an output terminal of the first MUX with a second data at an output terminal of the second ADC; and a plurality of switches (155) coupled between respective ones of the input terminals of the second MUX and a reference voltage node(154).
