Analog Devices Inc./Maxim Integrated MAX9202ESD+

Overview

The MAX9202ESD+ from Maxim Integrated is a dual high-speed voltage comparator with TTL-compatible outputs and latch inputs, designed for precision signal discrimination in mixed-signal systems. It delivers 7ns typical propagation delay (at 5mV overdrive), 9mW per comparator power consumption at +5V supply, and supports separate analog (±5V or +5V to +10V) and digital (+5V) supplies. It is used in high-speed A/D converters, line receivers, and PWM circuits where fast, low-power threshold detection with output hold capability is required.

For engineers reviewing the MAX9202ESD+ datasheet, MAX9202ESD+ pinout, MAX9202ESD+ application, or MAX9202ESD+ equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative comparators with documented functional and layout implications.

Technical Context

The MAX9202ESD+ integrates two independent comparators with internal active pullup TTL outputs and dedicated latch control inputs (LATCHA/LATCHB) that freeze output states on logic-low assertion. Its analog input common-mode range extends to the negative rail (VEE), enabling ground-referenced sensing under single-supply operation (VEE = GND).

It operates with fully decoupled analog (VCC/VEE) and digital (VDD) supplies - VCC supports +5V to +10V or ±5V configurations, while VDD is fixed at +5V. Propagation delay matching between channels is tightly controlled (∆tPD ≤ 2.5ns over temperature), and latch timing parameters (tS = 2ns, tN = 1ns, tPW(D) = 8ns) ensure reliable sampling synchronization in high-speed data acquisition.

Key Specifications

Pinout & Package

MAX9202ESD+ is housed in a 14-pin narrow SO (Small Outline) package with gull-wing leads, footprint compatible with industry-standard SOIC-14 but with reduced body width (3.9mm). Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-012 standard.

MAX9202ESD+ is available at Aetrix Electronics and suitable for high-speed A/D converter front-ends, industrial line receivers, and PWM-based motor control systems requiring stable component supply across extended temperature ranges and long production lifecycles.

Supply support for MAX9202ESD+ includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in high-performance analog, mixed-signal, and power-management ICs for industrial, communications, and computing applications.

The MAX9201/MAX9202/MAX9203 family was designed specifically for high-speed, low-power voltage comparison in data acquisition and signal conditioning systems where propagation delay, power efficiency, and latch synchronization are critical.

FAQ

What is the maximum operating temperature range for the MAX9202ESD+?

The MAX9202ESD+ is rated for continuous operation from –40°C to +85°C, with absolute maximum junction temperature of +150°C. This industrial-grade temperature range is validated across all electrical specifications in the datasheet, including propagation delay, input offset voltage, and latch timing parameters - ensuring reliable performance in motor drives, base station receivers, and factory automation equipment where ambient temperatures exceed 70°C.

Does the MAX9202ESD+ support single-supply operation with ground-referenced inputs?

Yes, the MAX9202ESD+ supports true single-supply operation: connect VEE to GND, apply +5V to +10V on VCC, and +5V on VDD. Its input common-mode range extends to VEE – 0.1V, allowing direct connection of grounded sensors or DAC outputs without level-shifting circuitry - a key advantage over comparators requiring input biasing above ground.

What is the function of pins 6 and 13 on the MAX9202ESD+?

Pins 6 and 13 on the MAX9202ESD+ are marked N.C. (No Connection) in the official pin description and contain no internal bond wire or circuit connection. These pins must remain unconnected on the PCB; routing traces or applying solder paste to them may cause mechanical stress or unintended coupling and is strictly prohibited per Maxim's assembly guidelines.

Can the MAX9202ESD+ drive standard TTL logic loads directly?

Yes, the MAX9202ESD+ features internally pulled-up TTL-compatible outputs capable of sourcing 1mA (VOH ≥ 3.0V) and sinking 8mA (VOL ≤ 0.4V), meeting LS-TTL specifications. Each output provides a fan-out of four, eliminating need for external pullup resistors in most digital interface applications - simplifying layout and reducing component count in high-density signal conditioning boards.

How does the latch feature of the MAX9202ESD+ improve timing accuracy in sampling circuits?

The latch inputs (LATCHA/LATCHB) on the MAX9202ESD+ freeze comparator outputs on the falling edge, capturing instantaneous analog conditions with sub-nanosecond timing resolution. With guaranteed tS = 2ns and tN = 1ns, the MAX9202ESD+ enables precise alignment of analog event capture to system clocks - critical for reducing aperture jitter in high-speed digitizers and ensuring deterministic behavior in real-time control loops.
