IPC: G01D5/12
Filed: 2012-01-18
Abstract: PROBLEM TO BE SOLVED: To provide a sensor threshold determination circuit that can output a digital value having hysteresis characteristics independent of sensor resistance, to external input of the sensor.SOLUTION: A sensor threshold voltage Vx is generated using the voltage of a terminal VPX or VNX as a reference potential by using a voltage drop which is a product of an output impedance RSUM1, RSUM2 of an impedance converter circuit 170 and a sensor bias current ±IB. Further, since impedance conversion resistors RSUM1, RSUM2 contain diffusion resistors, a sensor threshold determination circuit 20 can have a flat magnetic sensitivity with respect to temperature characteristics of the magnetic sensitivity. Thus, the sensor threshold determination circuit 20 can perform digital output having hysteresis characteristics independent of a sensor resistance R, to a sensor external input BIN.
