  • Patent number: 11828636
    Abstract: In a flow rate sensor 10, a resistance bridge 100 detects a change in a gas flow rate. A differential A/D converter 122 converts an analog signal output from the resistance bridge 100 into a digital signal. A disconnection detection circuit 130 detects disconnection of bonding wires 164, 165 that connect the differential A/D converter 122 and the resistance bridge 100. The disconnection detection unit 130 includes a detection capacitance 141 and a comparator 145. One connection portion of the detection capacitance 141 is connected to an input node of the A/D converter 122. The comparator 145 detects the disconnection of the bonding wires 164, 165 based on a potential based on a ratio of an electrostatic capacitance of a P-side input capacitance 116 or a N-side input capacitance 117 to an electrostatic capacitance of the detection capacitance 141. The P-side input capacitance 116 and the N-side input capacitance 117 respectively are connected to operation input units of the differential A/D converter 122.
