Overview
The MAX9107EKA+T is a dual, high-speed, low-power voltage comparator designed for single +5V supply operation. It features a propagation delay of 25ns with 10mV input overdrive and consumes only 350µA (1.75mW) 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 internal hysteresis ensures clean switching. It operates over a temperature range of -40°C to +85°C in an 8-pin SOT-23 package.
Feature Summary
- Incorporates internal hysteresis to ensure clean output switching even when driven by slow-moving input signals.
- Features TTL-compatible outputs that require no external pullup circuitry.
- Provides a wide input common-mode range that extends 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 '+T' corresponds to tape-and-reel packaging as indicated in official documentation. Confirm the manufacturer designation matches Analog Devices Inc./Maxim Integrated. Ensure the component meets RoHS compliance requirements specified for the part number. Cross-reference the datasheet revision to validate electrical characteristics against current production standards.
Selection Notes
Select this component for applications requiring fast response times with minimal power consumption on a single 5V supply. The dual-channel configuration in an 8-pin SOT-23 package is suitable for space-constrained designs. Consider the fixed internal hysteresis for noise immunity without external resistors. Verify that the TTL-compatible output levels align with the receiving logic family requirements.
Part Context
The MAX9107EKA+T belongs to the MAX9107/MAX9108/MAX9109 family of comparators. These devices serve as higher-speed, lower-power upgrades to the industry-standard MAX907/MAX908/MAX909 series. While the MAX9109 includes an internal latch, the MAX9107 focuses on dual-channel performance without complementary outputs or latching capabilities.
Replacement Considerations
Public confirmed substitute part numbers: MAX907ESA+, MAX907EKA+T, MAX908ESA+, MAX908EKA+T, MAX909ESA+, MAX909EKA+T.
FAQ
Does the MAX9107EKA+T include an internal latch?
No, the internal latch feature is exclusive to the MAX9109 variant within this family. The MAX9107 does not have complementary outputs or a latch.
What is the purpose of the internal hysteresis in the MAX9107?
The internal hysteresis eliminates oscillation in the linear region caused by noise or parasitic AC feedback, ensuring clean output switching even with slow-moving input signals without requiring external resistors.
