Overview
The MAX907ESA+ 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. Outputs are TTL-compatible, eliminating the need for external pullup resistors. Inputs and outputs support continuous short-circuit protection to either supply rail.
Feature Summary
- Built-in internal hysteresis ensures clean output switching without requiring external feedback components.
- TTL-compatible outputs provide direct logic interfacing capability without additional pullup circuitry.
- Input and output pins feature continuous short-circuit protection against both supply rails.
Applications
- Battery-powered systems
- High-speed A/D converters
- Threshold detectors and discriminators
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing lot codes if required by quality standards. Ensure the package matches the SO-8 specification. Review technical documentation for any design-in restrictions or obsolescence notices prior to final procurement decisions.
Selection Notes
Select this component for applications requiring low power consumption alongside high-speed response times in single-supply environments. The fixed internal hysteresis simplifies circuit design by removing the need for external resistor networks. Verify that the TTL-compatible output levels align with the receiving logic family requirements of the target system architecture.
Part Context
This part belongs to the MAX907/MAX908/MAX909 family of comparators manufactured by Maxim Integrated (now Analog Devices). While the datasheet indicates the MAX909 was produced using an unavailable foundry process and is not recommended for new designs, the MAX907 remains available. The series is characterized by its bipolar process technology and ultra-low power dissipation profile.
Replacement Considerations
Consult official documentation for industry second-source options or Maxim replacements suitable for new designs due to potential manufacturing process changes affecting older variants.
