Analog Devices Inc./Maxim Integrated MAX9013EUA+T

Overview

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

For engineers reviewing the MAX9013EUA+T datasheet, MAX9013EUA+T pinout, MAX9013EUA+T application, or MAX9013EUA+T equivalent, this page provides verified functional specifications, µMAX-8 package details, latch timing parameters (tSU = 2ns, tH = 0.5ns), and direct alternatives for single-supply, latched comparator designs requiring sub-10ns response and ground-sensing capability.

Technical Context

The MAX9013EUA+T uses a bipolar process with fully differential input amplifiers enabling operation with input common-mode voltage extending 200mV below ground and up to 1.9V below VCC. Its latch function is TTL-compatible and transparent when LE is low, holding output state when LE goes high - critical for synchronized sampling in data acquisition systems.

Unlike conventional high-speed comparators, it eliminates oscillation in the linear region without hysteresis, preserving resolution down to DC while maintaining 5ns propagation delay at 5mV overdrive. Complementary outputs (OUT/OUTB) provide inherent noise immunity and simplify interfacing with differential logic or clocked receivers.

Key Specifications

Pinout & Package

MAX9013EUA+T is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height), pin-compatible with industry-standard SO-8 but with 50% smaller footprint and improved thermal performance.

FAQ

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

The MAX9013EUA+T supports analog input voltages from -0.3V to (VCC + 0.3V) without permanent damage. This means at VCC = 5.5V, inputs may safely reach -0.3V to +5.8V. However, correct logic decisions require at least one input within the specified common-mode range of -0.2V to (VCC – 1.9V). The MAX9013EUA+T remains functional and phase-stable even when driven 200mV below ground, a key advantage for sensor interface applications.

Does the MAX9013EUA+T require external hysteresis for stable operation?

No, the MAX9013EUA+T does not require external hysteresis. Its internal architecture prevents oscillation in the linear region, enabling stable output behavior even with slow-moving or low-overdrive inputs. Adding hysteresis would degrade resolution - the MAX9013EUA+T achieves ±5.5mV offset and 5ns propagation delay without compromising either parameter, making it uniquely suited for precision DC-coupled threshold detection.

How does the latch enable (LE) pin function in the MAX9013EUA+T?

In the MAX9013EUA+T, the LE pin controls output transparency: when LE is low (≤0.8V), the comparator operates continuously and OUT/OUTB reflect real-time input comparisons; when LE is high (≥2V), the current output state is latched and held regardless of subsequent input changes. This enables synchronous sampling, such as capturing a voltage level at a precise clock edge - critical for data acquisition and digital control loops.

What is the thermal performance of the MAX9013EUA+T in its µMAX package?

The MAX9013EUA+T in the 8-pin µMAX package has a thermal resistance θJA of 222°C/W (calculated from 362mW max power dissipation at TA = +70°C with 4.5mW/°C derating). At 1.3mA quiescent current and 5V supply, typical power dissipation is ~6.5mW, resulting in negligible junction temperature rise (<1.5°C above ambient) - confirming suitability for thermally dense layouts without heatsinking.

Can the MAX9013EUA+T operate reliably with a 4.75V supply?

Yes, the MAX9013EUA+T is fully specified and guaranteed over 4.5V to 5.5V. At 4.75V, all key parameters remain valid: propagation delay stays ≤10ns (typical 5ns), output high voltage meets VOH ≥ 2.4V at 4mA load, and input common-mode range adjusts to -0.2V to 2.85V. Power supply rejection ratio (PSRR) of 63–82dB ensures minimal sensitivity to rail ripple, making the MAX9013EUA+T robust in marginally regulated 5V systems.
