The MAX9925AUB+ 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. It makes all three terminals of the internal operational amplifier suitable for greater flexibility gain.
