Maxim Integrated (MAX9927AEE+) Specialized Interface, Sensor Interface

Product OverviewThe MAX9927AEE+ is a variable reluctance sensor interface with differentialinput and adaptive peak threshold in 16 pin QSOP package. The variablereluctance (VR or magnetic coil) sensor interface device is ideal for positionand speed sensing for automotive crankshafts, camshafts and transmission shafts.This device integrates a precision amplifier and comparator with selectableadaptive peak threshold and zero crossing circuit blocks that generate robustoutput pulses even in the presence of substantial system noise or extremely weakVR signals. It makes all three terminals of the internal operational amplifiersuitable for greater flexibility gain.Supply voltage range is 4.5V to 5.5VOperating temperature range from -40°C to 125°CDifferential input stage provides enhanced noise immunityPrecision amplifier and comparator allows small signal detectionUser enabled internal adaptive peak threshold or flexible external thresholdZero crossing detection provides accurate phase informationSupply current is 4.7mAApplicationsCommunications & NetworkingProduct InformationIC Interface Type: Sensor InterfaceInterface Applications: Camshaft, Crankshaft & Vehicle Speed VRS InterfacesSupply Voltage Min: 4.5VSupply Voltage Max: 5.5VInterface Case Style: QSOPNo. of Pins: 16PinsOperating Temperature Min: -40°COperating Temperature Max: 125°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
