MAX9012EUA+T

Overview

The MAX9012EUA+T is a dual, high-speed analog comparator from the Maxim Integrated family. It operates on a single 4.5V to 5.5V supply and features low quiescent current consumption of 2.4mA. The device provides precision differential inputs with TTL-compatible outputs and a typical propagation delay of 5ns. It supports an input common-mode range extending to 0.2V below ground without output phase reversal. Packaged in an 8-pin µMAX format, it functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent high-speed comparators within a compact footprint
• Stable linear region operation that eliminates oscillation during slow-moving or low-overdrive signal transitions
• TTL-compatible push-pull outputs ensuring direct interface compatibility with standard digital logic circuits
• Extended common-mode input range allowing signals to operate slightly below ground potential

Applications

• High-speed signal squaring for waveform conversion
• Zero-crossing detection in AC signal processing
• High-speed line receivers for data transmission
• Fast pulse-width and height discriminators

Procurement Notes

Verify the specific ordering suffix '+T' against official manufacturer documentation to confirm tape-and-reel packaging status. Ensure the component matches the exact 'EUA' package designation. Cross-reference the datasheet revision number to validate electrical characteristics. Confirm RoHS compliance status through authorized distributor channels prior to final procurement decisions.

Selection Notes

Select this component when dual-channel comparison is required alongside strict space constraints. The µMAX package offers a smaller footprint compared to standard SOIC alternatives. Consider the 5ns propagation delay for timing-critical applications. Evaluate the 2.4mA supply current against system power budgets. Verify that the TTL output voltage levels align with the receiving logic family requirements.

Part Context

This part belongs to the MAX9010–MAX9013 series of precision TTL comparators manufactured by Analog Devices Inc./Maxim Integrated. The series includes single-channel variants (MAX9010, MAX9011) and complementary output models (MAX9013). The MAX9012 specifically provides dual channels without latch functionality or complementary outputs, distinguishing it within the product family.

Replacement Considerations

The MAX9013 serves as an improved plug-in replacement for industry-standard MAX913 and LT1016/LT1116 devices in single-supply applications.
