MAX913ESA+TG002

Overview

The MAX913ESA+ is a single-channel, ultra-fast, low-power precision TTL comparator manufactured by Analog Devices Inc./Maxim Integrated. It features differential inputs and complementary TTL outputs with a typical propagation delay of 10ns. The device operates from a single +5V or dual ±5V supply, drawing 6mA per comparator at +5V. Key electrical parameters include an input offset voltage of 0.8mV (typ), a common-mode rejection ratio of 110dB, and a power-supply rejection ratio of 100dB. It supports an extended input range that includes the negative rail and remains stable in the linear region without requiring hysteresis.

Feature Summary

• Ultra-fast response with 10ns typical propagation delay
• Stable operation in the linear region without oscillation
• Low power consumption with extremely low supply current
• Extended common-mode input range including the negative rail

Applications

• Zero-Crossing Detectors
• Switching Regulators
• High-Speed Sampling Circuits
• Fast Pulse Width/Height Discriminators

Procurement Notes

Verify the specific suffix 'TG002' against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts for SOIC-8 packages. Confirm RoHS compliance status through authorized distributors. Validate lead-free soldering requirements if applicable. Cross-reference part numbers with updated Analog Devices catalogs to avoid obsolete stock.

Selection Notes

Select this component for applications requiring high-speed comparison with minimal power dissipation. The wide common-mode input range allows flexibility in signal conditioning circuits. Consider the latch enable feature for holding output states during specific timing windows. Evaluate thermal performance within the specified operating temperature range. Ensure supply voltages align with the single or dual supply capabilities.

Part Context

The MAX913 is part of the MAX912/MAX913 family of high-speed comparators designed for low-power, high-speed applications. It serves as an improved plug-in replacement for older comparators like the LT1016, offering wider input voltage ranges and equivalent speed at lower power. The series is known for its stability in the linear region and precision TTL outputs.

Replacement Considerations

The datasheet identifies the MAX913 as an improved plug-in replacement for the LT1016. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in latch functionality or input range requirements.
