Overview
The MAX9107ESA+T is a dual, high-speed, low-power voltage comparator designed for single +5V supply systems. It features a 25ns propagation delay with 10mV input overdrive and consumes only 1.75mW per comparator. The device offers TTL-compatible outputs without external pullups and incorporates internal hysteresis for clean switching. Operating within a 4.5V to 5.5V range, it supports a wide input common-mode range extending from 200mV below ground to 1.5V of the positive rail. Available in an 8-pin SO package, it operates from -40°C to +85°C.
Feature Summary
- Incorporates internal hysteresis to ensure clean output switching even with slow-moving input signals.
- Features TTL-compatible outputs that require no external pullup circuitry.
- Provides a wide input common-mode range extending from 200mV below ground to within 1.5V of the positive supply rail.
Applications
- Battery powered systems
- A/D converters
- Line receivers
- Threshold detectors/discriminators
- Sampling circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Ensure the component matches the required pin configuration and electrical specifications for the target application. Cross-reference the manufacturer's part number with authorized distributor listings to confirm authenticity and current availability status before finalizing procurement decisions.
Selection Notes
Select this component when a dual-channel comparator with fast response times and low power consumption is required. It serves as a direct upgrade to industry-standard comparators like the MAX907/MAX908/MAX909 series. Consider its space-saving packages and integrated hysteresis for designs needing simplified circuit layouts and robust noise immunity in single-supply environments.
Part Context
The MAX9107 is part of the MAX9107/MAX9108/MAX9109 family of high-speed, low-power voltage comparators. While the MAX9107 provides dual channels, the MAX9108 offers quad channels and the MAX9109 provides a single channel with an internal latch. All variants share similar performance characteristics but differ in channel count and package options to suit various design constraints.
Replacement Considerations
The MAX9107 is documented as a higher-speed, lower-power, lower-cost upgrade to the MAX907/MAX908/MAX909 comparators. Verify compatibility regarding pinout and electrical parameters when substituting these legacy parts.
FAQ
Does the MAX9107 include an internal latch?
No, the internal latch feature is exclusive to the MAX9109 variant within the family.
What is the typical propagation delay of the MAX9107?
The propagation delay is 25ns with a 10mV input overdrive.
