Variable Reluctance Sensor Interfaces with

Differential Input and Adaptive Peak Threshold

4–MAX927

General Description

Features

The MAX9924–MAX9927 variable reluctance (VR or mag-

netic coil) sensor interface devices are ideal for position

and speed sensing for automotive crankshafts,

camshafts, transmission shafts, etc. These devices inte-

grate 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.

o Differential Input Stage Provides Enhanced Noise

Immunity

o Precision Amplifier and Comparator Allows

Small-Signal Detection

o User-Enabled Internal Adaptive Peak Threshold or

Flexible External Threshold

o Zero-Crossing Detection Provides Accurate

The MAX9926/MAX9927 are dual versions of the

MAX9924/MAX9925, respectively. The MAX9924/

MAX9926 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/MAX9926 differential amplifiers provide a fixed

gain of 1V/V. The MAX9925/MAX9927 make all three ter-

minals of the internal operational amplifier available,

allowing greater flexibility for gain. The MAX9926 also

provides a direction output that is useful for quadrature-

connected VR sensors that are used in certain high-per-

formance engines. These devices interface with both

new-generation differential VR sensors as well as legacy

single-ended VR sensors.
