Analog Devices Inc./Maxim Integrated MAX9013EUA

Overview

MAX9013EUA from Maxim Integrated is a single-channel, high-speed comparator with complementary TTL outputs and latch enable functionality, operating from a single 4.5V–5.5V supply. It delivers 5ns typical propagation delay, ±5.5mV max input offset voltage over –40°C to +85°C, and stable operation with slow-moving or low-overdrive inputs - ideal for precision zero-crossing detection and high-speed sampling circuits.

For engineers reviewing the MAX9013EUA datasheet, MAX9013EUA pinout, MAX9013EUA application, or MAX9013EUA equivalent, this device is selected for low-power, single-supply timing-critical systems requiring latch-hold capability, ground-sensing inputs, and deterministic output behavior without hysteresis or phase reversal.

Technical Context

The MAX9013EUA employs a fully differential bipolar input stage with no built-in hysteresis, enabling high-resolution comparison down to sub-millivolt differentials while remaining stable in the linear region. Its latch enable (LE) input provides synchronous output capture, with 2ns setup and 0.5ns hold time, and its complementary outputs (OUT/OUTB) support differential signaling or logic-level redundancy.

It features rail-to-rail common-mode input range extending 200mV below ground and up to 1.9V below VCC (3.3V total at 5V supply), with guaranteed operation across full industrial temperature range. Input bias current remains ≤±2µA and input capacitance is 1.5pF, minimizing loading on high-impedance sources.

Key Specifications

Pinout & Package

MAX9013EUA is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), pin-compatible with industry-standard SO-8 but with significantly reduced footprint and thermal resistance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed comparator applications.

Compared with MAX9013EUA, MAX913ESA lacks latch and complementary outputs - limiting use in synchronized sampling - while LT1016CS8#PBF mandates dual supplies and cannot accept inputs below ground, making both less suitable for modern compact, single-rail embedded timing systems.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog and mixed-signal ICs for industrial, medical, and communications applications, with emphasis on low-power, high-speed performance and robust operation.

The MAX9010–MAX9013 family was engineered specifically for single-supply, high-resolution timing applications demanding sub-10ns propagation delay, ground-referenced inputs, and latch-controlled output capture - targeting portable instrumentation and real-time control systems.

FAQ

What is the maximum input overdrive voltage supported by the MAX9013EUA without damage?

The MAX9013EUA allows analog inputs (IN+ or IN−) to swing from –0.3V to (V_CC + 0.3V) without permanent damage, per Absolute Maximum Ratings. This means at V_CC = 5.5V, inputs may reach +5.8V or –0.3V. However, correct logic decisions require at least one input within the specified common-mode range (–0.2V to V_CC – 1.9V). The MAX9013EUA remains functional and non-inverting even when driven 200mV below ground.

Does the MAX9013EUA require external hysteresis for stable operation?

No - the MAX9013EUA does not require external hysteresis. Its unique bipolar architecture ensures stable output behavior even when inputs reside in the linear region (e.g., near zero differential voltage), eliminating oscillation common to other high-speed comparators. Adding hysteresis would degrade resolution without benefit, as confirmed in the Applications Information section of the MAX9013EUA datasheet.

Can the MAX9013EUA operate from a 3.3V supply?

No - the MAX9013EUA is specified only for 4.5V to 5.5V single-supply operation. Electrical characteristics including propagation delay, input offset voltage, and output drive strength are guaranteed only within this range. Operation below 4.5V may result in undefined output states, increased delay, or failure to meet TTL output voltage thresholds (VOH ≥ 2.4V, VOL ≤ 0.6V), as verified in the MAX9013EUA ABSOLUTE MAXIMUM RATINGS and ELECTRICAL CHARACTERISTICS tables.

What is the purpose of the N.C. pin (Pin 7) on the MAX9013EUA µMAX package?

Pin 7 of the MAX9013EUA is explicitly designated "N.C." (No Connection) - it has no internal bond wire or circuit connection. Maxim recommends tying Pin 7 to GND to minimize parasitic capacitance and improve high-frequency noise immunity. Leaving it floating may increase susceptibility to EMI-induced glitches on adjacent pins, particularly LE and IN+ due to proximity in the µMAX layout.

How does the latch enable (LE) function interact with the complementary outputs of the MAX9013EUA?

When LE is driven high (≥2V), both OUT and OUTB outputs freeze in their current logic states - preserving the differential relationship between them. When LE is low (≤0.8V), both outputs respond dynamically to the IN+/IN− differential voltage in real time. The latch timing parameters (2ns setup, 0.5ns hold, 5ns propagation) apply identically to both outputs, ensuring simultaneous capture without skew - a key advantage over using two discrete comparators with separate latch controls.
