Overview
The MAX9107ESA is a dual, high-speed, low-power voltage comparator designed for single +5V supply operation. It features a propagation delay of 25ns with 1.75mW power consumption per comparator. The device 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 include internal hysteresis for clean switching. Operating voltage ranges from 4.5V to 5.5V, with an input offset voltage of 1.6mV max at 5V and bias current of 0.125µA max.
Feature Summary
- TTL-compatible outputs eliminate the need for external pullup circuitry
- Internal hysteresis ensures clean output switching with slow-moving signals
- 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 exact ordering suffix against the manufacturer's official documentation to confirm package type and RoHS status. Ensure the component matches the specific pinout and electrical characteristics required by the design. Cross-reference the datasheet revision date to confirm parameter validity. Confirm availability through authorized distributors or direct manufacturer channels.
Selection Notes
Select this component when a fast response time is critical alongside low power consumption in a single-supply environment. The fixed internal hysteresis simplifies circuit design by removing the need for external resistors. Verify that the required input signal range falls within the specified limits relative to ground and the positive supply rail.
Part Context
The MAX9107 is part of the MAX9107/MAX9108/MAX9109 family of comparators. It serves as a higher-speed, lower-power upgrade to the industry-standard MAX907/MAX908/MAX909 series. While the MAX9107 provides dual channels, other variants in the family offer quad or single configurations with different package options like TSSOP or SC70.
Replacement Considerations
The MAX907 is listed as a standard industry comparator that this device upgrades. Verify pin compatibility and electrical specifications before substituting.
