MAX9927AEE/V+T

Sensor And Detector Interfaces Overview

The MAX9927AEE/V+T is a dual-channel variable reluctance sensor interface designed for automotive applications. It operates on a 4.5V to 5.5V supply with a typical current of 4.7mA. The device features two differential input channels, each with an internally available operational amplifier allowing flexible external gain configuration. It includes adaptive peak threshold detection and zero-crossing circuits to generate robust logic pulses from weak or noisy VR signals. The component is qualified to AEC-Q100 standards and functions within a -40°C to +125°C temperature range. It is housed in a 16-pin QSOP package.

Sensor And Detector Interfaces Feature Summary

• Dual-channel architecture supporting independent variable reluctance sensor inputs
• Adaptive peak threshold mechanism ensures reliable signal detection across varying signal amplitudes
• Zero-crossing detection provides precise phase information for position sensing
• Flexible gain configuration via accessible internal operational amplifier terminals

Sensor And Detector Interfaces Applications

• Crankshaft variable reluctance sensor interfaces
• Camshaft variable reluctance sensor interfaces
• Vehicle speed sensor interfaces

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix /V confirms automotive qualification status as defined by the manufacturer. Confirm the package type matches the required QSOP-16 footprint. Ensure the RoHS compliance status aligns with project requirements. Cross-reference the datasheet revision to confirm pinout and electrical characteristics remain consistent with the design specification.

Sensor And Detector Interfaces Selection Notes

Select this part when dual-channel processing of variable reluctance sensors is required. Choose this model over single-channel variants if simultaneous crankshaft and camshaft monitoring is needed. Consider the external gain flexibility if signal conditioning requirements exceed the fixed-gain options provided by other family members. Verify that the automotive temperature range meets the specific engine bay environment constraints.

Sensor And Detector Interfaces Part Context

This component belongs to the MAX9924–MAX9927 family of variable reluctance sensor interfaces. It is the dual-channel variant corresponding to the single-channel MAX9925. While the MAX9926 offers similar dual-channel functionality, it includes a rotational direction output feature not present in the MAX9927. Both devices share the same 16-pin QSOP packaging and core signal processing capabilities.

Sensor And Detector Interfaces Replacement Considerations

The MAX9926UAEE/V+ is a direct functional substitute within the same family, offering identical dual-channel performance but including an additional rotational direction output pin.
