MAX989ESA

Comparators Overview

The MAX989ESA is a dual micro-power comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.5V to 5.5V or ±1.25V to ±2.75V. The device features rail-to-rail CMOS outputs and is housed in an 8-SOIC package. It exhibits low static current consumption, high input impedance with minimal bias current, and includes internal hysteresis for noise immunity.

Comparators Feature Summary

• Dual micro-power architecture designed for low energy consumption applications
• Rail-to-rail CMOS output capability compatible with TTL logic levels
• Integrated hysteresis to prevent output oscillation from noisy signals

Comparators Applications

• Battery-powered portable electronics requiring low quiescent current
• Threshold detection circuits in consumer devices
• Signal conditioning stages in microcontroller interfacing

Comparators Procurement Notes

Verify the specific suffix (e.g., +, T) against the manufacturer's official datasheet to confirm packaging and RoHS compliance status. Confirm availability through authorized distributors as lead times may vary. Ensure the selected variant matches the required operating temperature range and pinout configuration for your design.

Comparators Selection Notes

Select this component when dual comparators are needed in a compact SOIC package with ultra-low power requirements. Consider the rail-to-rail output swing if interfacing directly with digital logic inputs. Verify that the input common-mode voltage range aligns with your signal sources, especially near the supply rails.

Comparators Part Context

This part belongs to the MAX98x series of analog comparators from Maxim Integrated, now part of Analog Devices. The series focuses on providing precision comparison functions with minimized power usage, suitable for space-constrained and battery-operated systems where efficiency is critical.

Comparators Replacement Considerations

Check for direct replacements such as MAX989ESA+ or variants with tape-and-reel packaging like MAX989ESAT. Ensure functional equivalence regarding supply voltage, package type, and electrical characteristics before substitution.
