MAX9012ESA+T

Overview

The MAX9012ESA+T is a dual-channel, high-speed analog comparator manufactured by Analog Devices Inc. (Maxim Integrated). It operates from a single 4.5V to 5.5V power supply and features low quiescent current consumption of 2.4mA typical. The device provides precision differential inputs with an input offset voltage of 0.7mV typical at +25°C and TTL-compatible outputs. It exhibits a short propagation delay of 5ns typical and includes a wide common-mode input range that extends to 0.2V below ground. The component is housed in an 8-pin SO package and is guaranteed to operate over an extended temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent high-speed comparators within a single integrated circuit
• Stable operation through the linear region without oscillation, eliminating the need for minimum input signal slew-rate requirements
• TTL-compatible output logic levels ensuring direct interface compatibility with standard digital logic circuits
• Input voltage range extending below ground potential while maintaining stable output states without phase reversal

Applications

• High-speed signal squaring applications
• Zero-crossing detection circuits
• High-speed line receivers
• Fast pulse-width or height discriminators

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature rating. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Confirm RoHS compliance status matches project requirements before finalizing orders. Cross-reference the manufacturer part number with the latest datasheet revision to ensure all electrical specifications remain consistent with design expectations.

Selection Notes

Select this component when designing space-constrained systems requiring dual comparators with precise timing characteristics. The device is suitable for applications demanding high resolution without added hysteresis, as it remains stable during slow-moving input transitions. Consider the 8-pin SO package dimensions for PCB layout constraints. Evaluate the single-supply voltage range against available system power rails to ensure proper biasing conditions are met.

Part Context

This device belongs to the MAX9010–MAX9013 family of SC70, 5ns, low-power, single-supply, precision TTL comparators. The family includes single-channel variants like the MAX9010 and MAX9011, alongside the dual-channel MAX9012. All members share similar high-speed performance metrics and low-power characteristics tailored for modern electronic designs.

Replacement Considerations

The MAX9013 serves as an improved plug-in replacement for industry-standard parts such as the MAX913 and LT1016/LT1116 in single 5V supply applications, offering lower power consumption and higher speed capabilities.
