MAX9692EUB+

Comparators Overview

The MAX9692EUB+ is a single-channel, ultra-fast ECL-output comparator with latch enable functionality. It operates on +5V and -5.2V supplies within a -40°C to +85°C temperature range. Key electrical parameters include a typical propagation delay of 1.2ns, 100ps propagation delay skew, and 150ps dispersion. The device features differential inputs, complementary open-emitter outputs capable of driving 50Ω terminated transmission lines, and a latch-enable function for sample-hold mode operation.

Comparators Feature Summary

• Ultra-fast ECL-compatible output stage designed for signal processing at frequencies exceeding 600MHz.
• Integrated latch-enable function allows the comparator to operate in a sample-hold mode by forcing outputs to an unambiguous state based on input conditions at the latch transition.
• Maintains excellent DC matching characteristics typically found only in slower comparators despite high-speed operation.

Comparators Applications

• High-Speed Line Receivers
• Peak Detectors
• Threshold Detectors
• High-Speed Triggers

Comparators Procurement Notes

Verify the specific package variant (µMAX) against design requirements. Confirm power supply compatibility (+5V/-5.2V) and termination resistor values for ECL outputs. Ensure proper PCB layout with ground planes and microstrip routing to maintain signal integrity given the high gain-bandwidth product.

Comparators Selection Notes

Select this component when single-channel ultra-fast comparison with precise timing control is required. The latch-enable feature distinguishes it from standard comparators, making it suitable for applications requiring sampled data holding. Consider the µMAX package for space-constrained designs compared to SO or PDIP options.

Comparators Part Context

Part of the MAX9691/MAX9692/MAX9693 family of single/dual ultra-fast ECL comparators. The MAX9692 specifically provides one comparator channel with latch enable, whereas the MAX9691 lacks latch enable and the MAX9693 provides two channels. All share similar electrical performance characteristics.

Comparators Replacement Considerations

Direct functional substitutes within the same family include the MAX9691 (no latch) and MAX9693 (dual channel). Cross-family replacements require verification of ECL output compatibility, propagation delay specifications, and latch functionality if needed.

Comparators FAQ

How should unused Latch Enable pins be handled?

If the latch-enable function is not used, connect the LE pin to ground and the complementary LE input to a high ECL logic level.

What are the output drive capabilities?

The outputs are open emitters capable of driving 50Ω terminated transmission lines. External pull-down resistors (50Ω-200Ω to -2.0V or 240Ω-2000Ω to -5.2V) are required.
