MAX907EPA+

Overview

The MAX907EPA+ is a dual, high-speed, ultra-low-power voltage comparator designed for single +5V supply systems. It features a 40ns propagation delay with 5mV input overdrive and consumes only 3.5mW per comparator. The device operates within a 4.5V to 5.5V positive supply range and includes built-in hysteresis for clean switching. It offers a wide input common-mode range extending from 200mV below ground to within 1.5V of the positive rail. Outputs are TTL-compatible without external pullups, and inputs/outputs support continuous short-circuit protection.

Feature Summary

• Incorporates internal hysteresis to ensure clean output switching and prevent oscillation during slow-moving input signals.
• Features TTL-compatible outputs that require no external pullup circuitry for direct logic interfacing.
• Provides input and output short-circuit protection allowing continuous connection to either supply rail without damage.

Applications

• Battery-Powered Systems
• High-Speed A/D Converters
• Threshold Detectors/Discriminators

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity and pin alignment against the PDIP-8 specification. Review datasheet revisions for any updates regarding manufacturing processes or electrical characteristics prior to integration into final designs.

Selection Notes

Select this component for applications requiring high speed combined with low power consumption in single-supply environments. Ensure the design accommodates the specific input common-mode range limits. Consider thermal dissipation requirements if multiple comparators are utilized simultaneously within the same package.

Part Context

This part belongs to the MAX907/MAX908/MAX909 family of comparators manufactured by Analog Devices Inc./Maxim Integrated. The MAX907 specifically provides two independent comparator channels in an 8-pin configuration. It is distinct from the quad MAX908 and the single-channel MAX909 which includes additional latch functionality.

Replacement Considerations

The datasheet notes the MAX909 was manufactured using an unavailable process and is not recommended for new designs. Consult technical support for potential Maxim replacements or industry second-sources suitable for existing user upgrades.
