MAX9927AEE/V+

Sensor And Detector Interfaces Overview

The MAX9927AEE/V+ is a dual-channel variable reluctance sensor interface designed for automotive crankshaft and camshaft position sensing. It operates on a 4.5V to 5.5V supply with a typical current of 4.7mA. The device integrates two precision operational amplifiers and comparators within a 16-pin QSOP package, specified over the -40°C to +125°C temperature range. Key electrical parameters include a common-mode rejection ratio up to 102dB, an input offset voltage of 3mV maximum, and propagation delays of 50ns to 150ns depending on the signal path.

Sensor And Detector Interfaces Feature Summary

• Dual-channel architecture supporting independent differential amplifier configurations
• Internal adaptive peak threshold mechanism for robust noise immunity
• Zero-crossing detection capability providing accurate phase information
• Open-drain comparator outputs compatible with various microcontroller logic levels

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 AEC-Q100 automotive qualification status before integration. Confirm the QSOP-16 package dimensions match the target PCB footprint. Ensure the design supports the required external bias network or utilizes Mode A2 internal reference as needed for the application environment.

Sensor And Detector Interfaces Selection Notes

Select this component when dual-channel VR signal processing is required. Unlike the MAX9926, this model lacks a rotational direction output but offers flexible external gain settings via its accessible op-amp terminals. Verify that the system can accommodate the necessary external resistors for the differential amplifier configuration in Modes B and C.

Sensor And Detector Interfaces Part Context

This part belongs to the MAX9924–MAX9927 family of variable reluctance sensor interfaces. While the MAX9924/26 feature integrated matched resistors for fixed gain, the MAX9925/27 models expose all operational amplifier terminals. This allows designers to set custom gain values using external components, providing greater flexibility for varying sensor signal amplitudes.

Sensor And Detector Interfaces Replacement Considerations

The MAX9926UAEE/V+ serves as a functional substitute if rotational direction output is required instead of flexible gain. The MAX9927AEE+ is available without automotive qualification. Single-channel alternatives include the MAX9924 and MAX9925 series.
