Analog Devices Inc./Maxim Integrated MAX9692ESE

Overview

MAX9692ESE from Maxim Integrated is a single-channel, ultra-fast ECL-output comparator with latch-enable functionality, designed for high-speed signal conditioning in timing-critical systems. It delivers 1.2ns typical propagation delay, 100ps skew, and operates from +5V and -5.2V supplies. Its open-emitter outputs drive 50Ω-terminated transmission lines and support >600MHz signal processing in applications such as high-speed line receivers and threshold detection.

For engineers reviewing the MAX9692ESE datasheet, MAX9692ESE pinout, MAX9692ESE application, or MAX9692ESE equivalent, this device is selected for sub-2ns timing precision, ECL-compatible differential inputs/outputs, latch-controlled sampling, and SO-16 package compatibility with high-density PCB layouts.

Technical Context

The MAX9692ESE implements a BiCMOS-based ECL comparator core with fully differential input stage and complementary open-emitter outputs. Its latch-enable (LE) input enables sample-hold operation: LE high permits normal comparison; LE low freezes output states based on instantaneous input conditions at the falling edge.

It requires external pull-down resistors (50Ω–200Ω to -2.0V or 240Ω–2000Ω to -5.2V) on Q and Q̅ outputs, and mandates separate GND1 (input bias) and GND2 (output bias) connections. Input common-mode range spans -2.5V to +3.0V, supporting wide-swing ECL signaling under ±5.2V/5V dual-rail operation.

FAQ

What is the recommended power supply configuration for MAX9692ESE?

The MAX9692ESE requires dual supplies: +5V on VCC (Pin 1) and -5.2V on VEE (Pin 4). Each supply must be bypassed locally with a 0.1µF ceramic capacitor to GND. The specified operating range is -40°C to +85°C, and the device draws up to 36mA total supply current across temperature. Deviations outside these rails risk violating absolute maximum ratings and degrading propagation delay consistency.

How should unused latch-enable pins be terminated on MAX9692ESE?

On MAX9692ESE, Pin 11 is the functional latch-enable (LE) input, and Pin 12 is its complementary LE input-unused in single-comparator mode. Pin 12 must be tied to an ECL-high logic level (e.g., -1.0V via a pull-up resistor to VCC), not left floating. Leaving Pin 12 unconnected may cause undefined output behavior or increased susceptibility to noise-induced false latching.

What external components are mandatory for MAX9692ESE output interfacing?

MAX9692ESE features open-emitter Q and Q̅ outputs (Pins 5 and 6) that require external pull-down resistors. For -2.0V termination, use 50Ω–200Ω resistors; for -5.2V termination, use 240Ω–2000Ω. These resistors establish proper ECL logic levels and match 50Ω transmission lines. No internal termination exists-omitting them results in non-functional outputs.

Does MAX9692ESE support operation with input signals outside the common-mode range?

Yes-the MAX9692ESE will not false trip if one input resides within the valid common-mode range (-2.5V to +3.0V) while the other is outside it. This robustness prevents erroneous switching during signal acquisition transients or fault conditions, making MAX9692ESE suitable for applications like overvoltage protection where asymmetric input excursions occur.

What is the significance of separate GND1 and GND2 pins on MAX9692ESE?

GND1 (Pin 8) biases the input differential pair; GND2 (Pin 7) biases the ECL output stage. They must be connected to the same solid copper ground plane but routed separately to prevent output-stage switching noise from modulating input bias. Failure to isolate these grounds increases propagation delay variation and degrades skew performance in MAX9692ESE.
