MAX9926UAEE+T

Sensor And Detector Interfaces Overview

The MAX9926UAEE+T is a dual-channel variable reluctance sensor interface device designed for automotive position and speed sensing applications. It operates within a supply voltage range of 4.5V to 5.5V, with typical operating currents of 4.7mA and a maximum of 10mA. The device features two differential input stages with a fixed gain of 1V/V and integrated precision matched resistors. Key electrical specifications include a common-mode rejection ratio (CMRR) of up to 78dB and an input offset voltage of 3mV maximum. It supports an extended automotive temperature range from -40°C to +125°C and is housed in a 16-pin QSOP package.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix to confirm automotive qualification status. The base part number indicates standard commercial grade, while the /V suffix denotes AEC-Q100 qualified parts suitable for automotive environments. Ensure the tape-and-reel packaging matches the production line requirements. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Sensor And Detector Interfaces Selection Notes

Select this component when dual-channel variable reluctance sensing is required with integrated signal conditioning. The fixed 1V/V gain simplifies external circuit design compared to externally configurable amplifier variants. Verify that the 16-pin QSOP package fits the available PCB footprint. Consider the adaptive threshold functionality if the application environment exhibits significant electromagnetic interference or signal amplitude variations.

Sensor And Detector Interfaces Part Context

This device belongs to the MAX9924–MAX9927 family of variable reluctance sensor interfaces. It serves as the dual-channel counterpart to the single-channel MAX9924, sharing identical internal architecture but providing two independent signal paths. The family is specifically engineered for harsh automotive environments, offering integrated biasing and threshold management to reduce external component count.

Sensor And Detector Interfaces Replacement Considerations

The MAX9926UAEE+ is the non-automotive qualified version of this component. For direct pin-compatible replacement, verify that the application does not require AEC-Q100 certification. No other cross-model replacements are documented in the official datasheet.
