MAX9017AEKA

Overview

The MAX9017AEKA is a dual precision analog comparator manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an SOT-23-8 surface-mount package. It operates within a supply voltage range of 1.8V to 5.5V and features a push-pull CMOS output capable of driving up to 50mA. Key electrical specifications include a maximum input offset voltage of 5mV at 5V, a typical quiescent current of 2.8µA, and a propagation delay of 28µs. The device includes internal hysteresis of 4mV and meets AEC-Q100 automotive qualification standards for operation between -40°C and +85°C.

Feature Summary

• Dual-channel precision comparison with integrated reference capabilities
• Ultra-low power consumption suitable for battery-operated systems
• Automotive-grade reliability compliant with AEC-Q100 standards
• Push-pull rail-to-rail output stage for direct logic interfacing

Applications

• Battery-powered portable electronic devices requiring low standby current
• Automotive sensor signal conditioning and threshold detection
• Over-voltage and under-voltage protection circuits
• Temperature monitoring systems with precise trip points

Procurement Notes

Verify the specific suffix (e.g., /V+T) against the manufacturer's official datasheet to confirm pinout compatibility and packaging type. Ensure the component meets the required AEC-Q100 grade if used in automotive applications. Cross-reference the lot date code to verify freshness and storage conditions. Confirm RoHS compliance status through the supplier's certificate of conformity prior to integration into production assemblies.

Selection Notes

Select this component when design constraints demand minimal quiescent current alongside high accuracy in a compact footprint. The SOT-23-8 package offers space efficiency compared to larger SOIC options. Consider the 28µs propagation delay as a limiting factor for high-speed switching applications; it is optimized for precision rather than speed. Verify that the 50mA output drive capability matches the load requirements without external buffering.

Part Context

This part belongs to the MAX9017 series of nanopower comparators designed for low-voltage operation. It serves as a specialized alternative to general-purpose comparators that require higher supply voltages or consume more power. The series integrates precision trimming to minimize offset voltage, making it distinct from standard operational amplifiers repurposed for comparison tasks.

Replacement Considerations

Check for MAX9017 variants with different temperature grades or packaging suffixes. Verify functional equivalence regarding output drive strength and offset voltage specifications before substituting.
