MAX9012ESA+

Overview

The MAX9012ESA+ is a dual-channel, high-speed analog comparator from the Maxim Integrated family. It operates on a single 4.5V to 5.5V supply with a typical quiescent current of 2.4mA per device. The component features ultra-fast propagation delay of 5ns and high-precision inputs with a typical offset voltage of 0.7mV. It provides TTL-compatible outputs and supports an input common-mode range extending 200mV below ground. Designed for space-critical applications, it is housed in an 8-pin SO package and functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Ultra-fast 5ns propagation delay for high-speed signal processing
• High precision with low input offset voltage and wide common-mode range including ground
• Stable operation without oscillation in the linear region, eliminating minimum slew-rate requirements
• TTL-compatible outputs suitable for direct digital logic interfacing

Applications

• High-speed signal squaring circuits
• Zero-crossing detectors
• Fast pulse-width or height discriminators
• High-speed sampling circuits

Procurement Notes

Verify the specific suffix 'ESA+' against official manufacturer documentation to confirm the exact package type (SOIC) and lead-free compliance status. Ensure that the ordering information matches the required pin configuration and thermal characteristics for your specific board layout constraints before finalizing procurement.

Selection Notes

Select this component when a dual-channel comparator with sub-nanosecond jitter and high precision is required. It is suitable for designs needing stable performance with slow-moving signals or low overdrive conditions. Consider the 8-pin SO package dimensions and the 4.5V to 5.5V supply requirement during the initial schematic capture phase.

Part Context

This part belongs to the MAX9010–MAX9013 series of single-supply precision comparators. While the MAX9010 and MAX9011 are single-channel devices, the MAX9012 provides two independent channels in a compact footprint. The MAX9013 variant offers complementary outputs and latch functionality, distinguishing it from the standard output configuration found in the MAX9012.
