MAX9924
Description
The MAX9924-MAX9927 variable reluctance (VR or magnetic coil) sensor interface devices are ideal for position and speed sensing for automotive crankshafts, camshafts, transmission shafts, etc. These devices integrate 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.
Key Features
- 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
