com NCV1124 Dual Variable−Reluctance Sensor Interface IC The NCV1124 is a monolithic integrated circuit designed primarily to condition signals from sensors used to monitor rotating parts.
The NCV1124 is a dual channel device.
Each of the two identical channels interfaces with a variable−reluctance sensor, and continuously compares the sensor output signal to a user−programmable internal reference.
An alternating input signal of appropriate amplitude at IN1 or IN2 will result in a rectangular waveform at the corresponding OUT terminal, suitable for interface to either standard microprocessors or standard logic families.
A diagnostic input, common to both channels, provides a means to test for degradation or loss of the physical connector to both sensors.
