Overview
The MAX907ESA+T is a dual, high-speed, ultra-low-power voltage comparator designed for single +5V supply systems. It features a typical propagation delay of 40ns with 5mV input overdrive and consumes only 3.5mW per comparator. The device operates within a supply range of 4.5V to 5.5V and supports an input common-mode range extending from 200mV below ground to within 1.5V of the positive rail. It incorporates internal hysteresis for clean switching and provides TTL-compatible outputs without external pullup resistors.
Feature Summary
- Ultra-low power consumption of 3.5mW per comparator at 5V operation
- High-speed performance with 40ns typical propagation delay
- Built-in internal hysteresis eliminates need for external feedback components
- TTL-compatible push-pull outputs require no external pullup circuitry
Applications
- Battery-powered systems requiring low current draw
- High-speed analog-to-digital converter interfaces
- Threshold detectors and discriminators
- Zero-crossing detection circuits
Procurement Notes
Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any updates to electrical characteristics or ordering information. Ensure storage conditions comply with manufacturer specifications to maintain reliability.
Selection Notes
Select this component for applications demanding both speed and minimal power dissipation in single-supply environments. Consider the MAX908 for quad configurations or MAX909 for single-channel needs with latch functionality. Evaluate PCB layout requirements for low-inductance grounding to maximize high-speed performance.
Part Context
Part of the MAX907/MAX908/MAX909 family of comparators manufactured by Maxim Integrated, now part of Analog Devices. These devices replace older comparator technologies by integrating precision and speed into micropower designs. The MAX907 specifically offers dual channels in compact DIP and SO packages.
Replacement Considerations
The MAX909 was noted as not recommended for new designs due to process availability issues. Consult technical support for potential second-source alternatives or modern replacements compatible with existing designs.
