MAXIM INTEGRATED PRODUCTS MAX9924UAUB+T 专用接口, 传感器接口, 凸轮轴, 曲轴和车速VRS接口, 4.5 V, 5.5 V, µMAX, 10 引脚
The is a variable reluctance sensor interface with differential input and adaptive peak threshold in 10 pin µMAX package. The variable reluctance VR or magnetic coil sensor interface device is ideal for position and speed sensing for automotive crankshafts, camshafts and transmission shafts. This device integrates a precision amplifier and comparator with selectable adaptive peak threshold and zero crossing circuit blocks that generate robust output pulses even in the presence of substantial system noise or extremely weak VR signals. The MAX9924 combine matched resistors with a CMOS input precision operational amplifier to give high CMRR over a wide range of input frequencies and temperatures. The MAX9924 differential amplifier provides a fixed gain of 1V/V.
