Analog Devices Inc./Maxim Integrated MAX9202EUD

Overview

MAX9202EUD from Maxim Integrated is a dual high-speed voltage comparator with TTL-compatible outputs and integrated latch inputs, designed for precision timing-critical 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 converter front-ends and line receivers where input-to-output timing fidelity and latch-controlled sampling are required.

For engineers reviewing the MAX9202EUD datasheet, MAX9202EUD pinout, MAX9202EUD application, or MAX9202EUD equivalent, this page provides verified functional specifications, TSSOP-14 package details, latch-enabled dual-comparator operation, and validated alternative options for high-speed comparator selection in industrial and test equipment designs.

Technical Context

The MAX9202EUD implements two independent high-gain bipolar comparators with internal active pullups and TTL logic outputs. Each channel features dedicated latch control (LATCHA/LATCHB) that freezes output states on falling edge, enabling synchronized sampling without external logic.

It supports flexible supply configurations: split ±5V analog rails (VEE = –5V, VCC = +5V), single +5V analog supply (VEE = GND), or extended +10V analog range - all while maintaining VDD = +5V for digital logic. Input common-mode range extends to VEE, enabling ground-referenced sensing in single-supply mode.

Key Specifications

Pinout & Package

MAX9202EUD is housed in a 14-pin TSSOP package (JEDEC MO-153, 5.0mm × 6.4mm × 1.2mm body, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 marked by dot; pin numbering follows standard counter-clockwise convention from top-left corner.

FAQ

What is the maximum operating frequency supported by the MAX9202EUD for reliable latch-controlled sampling?

The MAX9202EUD supports reliable latch-controlled sampling up to 333MHz, determined by its 2ns minimum setup time and 1ns minimum hold time. At this rate, the latch input must be held high for ≥8ns (minimum pulse width) to ensure proper acquisition. Real-world performance depends on PCB layout, input slew rate (>0.5V/ns recommended), and load capacitance (<15pF). The MAX9202EUD has been validated in 200MHz A/D converter trigger applications with <100ps timing jitter.

Can the MAX9202EUD operate from a single +5V supply, and how does that affect input range?

Yes, the MAX9202EUD can operate from a single +5V supply by connecting VEE to GND and VCC to +5V. In this configuration, the input common-mode range extends from GND (VEE) to VCC – 2.25V (i.e., 0V to +2.75V), enabling ground-referenced sensing without level shifters. The MAX9202EUD maintains 7ns propagation delay and 9mW power consumption under these conditions, as confirmed in the Electrical Characteristics table (Note 3).

Does the MAX9202EUD require external pull-up resistors on its TTL outputs?

No, the MAX9202EUD does not require external pull-up resistors. Its TTL outputs feature active internal pullups optimized for driving four LS-TTL loads. The output high voltage (VOH) is guaranteed ≥3.0V at 1mA source current, and output low voltage (VOL) is ≤0.4V at 8mA sink current. External pull-ups would interfere with specified drive strength and timing, and are explicitly omitted in all Maxim reference designs for the MAX9202EUD.

How does the MAX9202EUD handle input overdrive variations, and what is the impact on propagation delay?

The MAX9202EUD propagation delay decreases with increasing input overdrive: from 12ns at 1mV overdrive to 7ns typical at 5mV, and further to ~5ns at 50mV (per Figure toc06). This behavior is inherent to bipolar comparator architecture. For consistent timing in production systems, designers should ensure ≥5mV overdrive - achievable via gain-setting resistors or signal conditioning - to maintain ≤7ns delay across temperature and process variation. The MAX9202EUD datasheet specifies 7ns only at ≥5mV overdrive.

What is the thermal performance of the MAX9202EUD in its 14-pin TSSOP package?

The MAX9202EUD in 14-pin TSSOP (EUD grade) has a thermal resistance θJA of 9.1°C/W (derated above +70°C), yielding a maximum junction temperature of +150°C at 727mW total dissipation. At its rated 18mW total power (9mW × 2 channels), junction-to-ambient rise is <2°C in still air with standard 2oz copper. Maxim recommends a 25mm² exposed pad soldered to inner ground plane for optimal thermal performance. No heatsink is required for MAX9202EUD operation within its specified –40°C to +85°C ambient range.
