Overview
The MAX907ESA 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 circuitry. The component is housed in an 8-pin SO package.
Feature Summary
- Ultra-low power consumption of 3.5mW per comparator at 5V supply
- High-speed performance with 40ns propagation delay under specified conditions
- Built-in internal hysteresis eliminates need for external resistors
- TTL-compatible outputs require no external pullup components
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 that the specific order includes the '+' suffix, indicating compliance with RoHS standards. Confirm the 'E' designation corresponds to the -40°C to +85°C industrial temperature range. Ensure the 'SA' suffix matches the required 8-pin SO plastic package. Check for manufacturer notices regarding new design recommendations due to process availability changes.
Selection Notes
Select this component when a combination of high speed and minimal power dissipation is critical for single-supply applications. The fixed internal hysteresis simplifies circuit layout by removing external feedback resistors. Verify that the required propagation delay and offset voltage specifications align with the system's timing and precision requirements.
Part Context
The MAX907 is part of the MAX907/MAX908/MAX909 family of comparators manufactured by Maxim Integrated. While the datasheet remains available for existing users, the manufacturing process for the MAX909 has been discontinued. The MAX907 itself continues to be produced in 8-pin DIP and SO packages for dual-channel comparison tasks.
Replacement Considerations
Consult technical support or official documentation for recommended industry second-sources or Maxim replacements suitable for new designs.
