MAX9924UAUB+T

The MAX9924UAUB+T 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.

• Supply voltage range is 4.5V to 5.5V
• Operating temperature range from -40°C to 125°C
• Differential input stage provides enhanced noise immunity
• Precision amplifier and comparator allows small signal detection
• User enabled internal adaptive peak threshold or flexible external threshold
• Zero crossing detection provides accurate phase information
• Supply current is 2.6mA
