MAX9926UAEE+T

MAX9926UAEE+T is a variable reluctance (VR or magnetic coil) sensor interface device that is ideal for position and speed sensing for automotive crankshafts, camshafts, transmission shafts, etc. 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 MAX9926 also provides a direction output that is useful for quadrature-connected VR sensors that are used in certain high performance engines. Applications include camshaft VRS interfaces, crankshaft VRS interfaces, and vehicle speed VRS interfaces.
