MAX9107ESA-T

Overview

The MAX9107ESA-T is a dual, 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 350µA per comparator. The device operates within a supply voltage range of 4.5V to 5.5V. It incorporates internal hysteresis of 2mV to ensure clean output switching. The inputs support a wide common-mode range extending from 200mV below ground to within 1.5V of the positive rail. Outputs are TTL-compatible without requiring external pullup circuitry.

Feature Summary

• Incorporates internal hysteresis to prevent oscillation and ensure clean switching during slow-moving input transitions.
• Features TTL-compatible outputs that eliminate the need for external pullup resistors or additional logic interface components.
• Supports a wide input common-mode voltage range that includes ground potential, facilitating direct connection to various signal sources.

Applications

• Battery powered systems
• A/D converters
• Line receivers
• Threshold detectors/discriminators
• Sampling circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the package type matches the required 8-pin SOIC footprint for your PCB layout. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component for applications requiring fast response times with minimal power consumption in single-supply environments. It serves as an upgrade to industry-standard comparators like the MAX907 series. Consider the internal hysteresis feature if external noise filtering is desired. Verify that the TTL output levels align with the receiving logic family requirements.

Part Context

This part belongs to the MAX9107/MAX9108/MAX9109 family of comparators. The MAX9107 specifically provides two independent channels in a compact package. It is positioned as a higher-speed, lower-power alternative to legacy devices. The family shares similar electrical characteristics but varies in channel count and package options.

Replacement Considerations

The datasheet identifies the MAX907, MAX908, and MAX909 as industry-standard comparators upgraded by this series. These legacy parts may serve as functional replacements in existing designs, though performance metrics will differ. Verify pin compatibility and electrical specifications before substituting.
