MAX907C/D

Overview

The MAX907C/D is a high-speed, ultra low-power voltage comparator manufactured by Analog Devices Inc./Maxim Integrated. It features a propagation delay of 40ns with 5mV input overdrive and consumes only 3.5mW per comparator. The device operates from a single +5V supply (4.5V to 5.5V) or dual ±5V supplies. Key electrical parameters include a wide input common-mode range extending from 200mV below ground to within 1.5V of the positive rail, a low offset voltage of 500µV, and TTL-compatible outputs. It includes internal hysteresis for clean switching and input/output short-circuit protection.

Feature Summary

• Ultra low-power operation with 3.5mW consumption per comparator
• High-speed performance with 40ns propagation delay
• Wide input common-mode range including ground reference
• Internal hysteresis ensures clean switching transitions

Applications

• Battery-powered systems
• High-speed A/D converters
• Threshold detectors and discriminators
• Zero crossing detectors

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm package type matches design requirements as the part is available in die form. Check current lifecycle status as older Maxim products may face obsolescence. Ensure supply chain stability for production continuity given the component's age.

Selection Notes

Select this comparator for applications requiring minimal power consumption alongside fast response times. The single-supply operation simplifies power management in portable devices. Consider the wide input range when interfacing with sensors operating near ground potential. Verify that the TTL-compatible output levels match downstream logic requirements.

Part Context

The MAX907 series belongs to Maxim Integrated's family of high-speed comparators designed for single-supply applications. It complements the MAX908 and MAX909 variants which offer quad and single-channel configurations respectively. The C/D suffix typically denotes commercial temperature range and die packaging options.

Replacement Considerations

Direct replacements include MAX908 and MAX909 for different channel counts. Verify pin compatibility and electrical specifications before substitution. Consider newer generations of comparators if lower power or higher speed is required.
