Overview
The MAX9108EUD+ is a quad, high-speed, low-power voltage comparator designed for single +5V supply systems. It features a propagation delay of 25ns with 10mV input overdrive and consumes only 1.75mW per comparator. The device operates within a 4.5V to 5.5V supply range and 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 internal hysteresis ensures clean switching.
Feature Summary
- Quad configuration in a 14-pin TSSOP package
- TTL-compatible outputs requiring no external pullup circuitry
- Internal hysteresis eliminates external resistors for noise immunity
- Wide input common-mode range includes ground potential
Applications
- Battery powered systems
- A/D converters
- Line receivers
- Threshold detectors/discriminators
- Sampling circuits
- Zero-crossing detectors
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the component matches the required operating temperature range of -40°C to +85°C for your application environment before finalizing procurement.
Selection Notes
Select this component when a quad comparator topology is required alongside low power consumption and fast response times. The fixed internal hysteresis simplifies design by removing the need for external feedback resistors. Verify that the system operates on a single +5V supply, as the device is optimized for this voltage range and does not support dual supplies or lower voltage rails.
Part Context
This part belongs to the MAX9107/MAX9108/MAX9109 family of comparators. The MAX9108 specifically provides four independent channels in a compact footprint. It serves as an upgrade to older industry-standard parts like the MAX908, offering higher speed and lower cost while maintaining compatibility with standard logic interfaces.
Replacement Considerations
The MAX9108ESD+ is a pin-compatible SO package alternative within the same family.
