MAX988ESA

Comparators Overview

The MAX988ESA+ is a high-speed, micropower, low-voltage analog comparator manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.5V to 5.5V and features a single channel in an 8-pin SOIC package. The device offers a propagation delay of 450ns maximum and a quiescent current of 24µA. Input offset voltage is specified at 5mV maximum at 5.5V, with input bias current as low as 1pA. It supports CMOS, open-drain, rail-to-rail, and TTL output types.

Comparators Feature Summary

• High-speed operation with low power consumption suitable for battery-powered applications
• Low input bias current and low input offset voltage for precision signal comparison
• Versatile output configuration supporting multiple logic families including CMOS and TTL

Comparators Applications

• Battery-powered sensing systems requiring low quiescent current
• Threshold detection circuits in portable electronic devices
• Signal conditioning stages in low-voltage data acquisition systems

Comparators Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as the part may be subject to discontinuation. Ensure the ordering suffix matches the required packaging format. Validate datasheet revisions against the specific production batch to ensure parameter consistency.

Comparators Selection Notes

Select this comparator when low power consumption and high speed are critical requirements within a single-supply environment. Consider the 8-SOIC package constraints for PCB layout. Evaluate the trade-off between the 450ns propagation delay and the 24µA supply current against alternative comparators if faster switching speeds are necessary for the target application.

Comparators Part Context

The MAX988 belongs to the Maxim Integrated family of micropower comparators designed for general-purpose use. It complements other parts like the MAX986 and MAX989 by offering a balance of speed and power efficiency. The series is characterized by its ability to operate from a single supply voltage while maintaining performance suitable for consumer and industrial electronics.

Comparators Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX986ESA+ or MAX989ESA+. Verify that substitute components meet the same voltage range and package requirements. Review updated datasheets for any changes in electrical characteristics or availability status before finalizing the replacement.
