The MAX9924UAUB+ from Analog Devices is a Sensor Interface Variable-Reluctance Sensor Interface with Differential Input and Adaptive Peak Threshold. It features an adjustable threshold, an internal comparator with hysteresis algorithm for adaptive peak detection, internal lowpass filter for noise rejection, and spike suppression. It is designed for use in wide range of automotive applications, such as detection of rotating speed, angular position, cam-mode crank positions, crankshaft position, and other variable reluctance devices. The MAX9924UAUB+ can be operated from a single 5V supply and incorporates an internal voltage regulator, allowing it to be used in a variety of systems.
