Analog Devices Inc./Maxim Integrated MAX913EUA-T

Overview

The MAX913EUA-T from Maxim Integrated is a single, ultra-fast, low-power precision TTL comparator with differential inputs and complementary TTL outputs. It delivers 10ns typical propagation delay, ±5V or +5V single-supply operation, input voltage range extending below the negative rail (–0.2V to +3.5V on +5V supply), and stable linear-region operation-making it ideal for high-speed zero-crossing detection and switching regulator feedback in industrial power systems.

For engineers reviewing the MAX913EUA-T datasheet, MAX913EUA-T pinout, MAX913EUA-T application, or MAX913EUA-T equivalent, key selection criteria include propagation delay stability under slow-slew inputs, latch-enable functionality for synchronized sampling, input common-mode range compatibility with ±5V or single +5V rails, and µMAX package suitability for space-constrained PCB layouts.

Technical Context

The MAX913EUA-T uses a fully differential bipolar input amplifier with laser-trimmed offset (0.8mV typ) and no built-in hysteresis, enabling high-resolution comparison of low-frequency or slowly varying signals without oscillation in the linear region. Its latch-enable (LE) pin provides transparent or latched output control independent of input slew rate.

It operates from either a single +5V supply (V− = GND) or dual ±5V supplies (V− = –5V), with input common-mode range spanning –5.2V to +3.5V under dual supply and –0.2V to +3.5V under single supply. Output stages deliver TTL-compatible VOH ≥ 2.4V (IOUT = 10mA) and VOL ≤ 0.5V (ISINK = 10mA), ensuring direct interfacing with standard logic families.

FAQ

What supply voltages does the MAX913EUA-T support?

The MAX913EUA-T operates from a single +5V supply (with V− connected to GND) or dual ±5V supplies (V+ = +5V, V− = –5V). It tolerates V+ from +4.5V to +5.5V and V− from –7V to 0V. The MAX913EUA-T maintains full specification compliance across this range, including 10ns propagation delay and stable linear-region behavior, making it adaptable to both legacy ±5V systems and modern single-rail designs.

Does the MAX913EUA-T require external hysteresis for stable operation?

No-the MAX913EUA-T is explicitly designed to remain stable in its linear region without hysteresis. Its internal architecture prevents oscillation during slow-moving or near-threshold inputs, unlike many high-speed comparators. Adding external hysteresis degrades resolution and is unnecessary; the MAX913EUA-T achieves clean, jitter-free output transitions even with DC or millihertz-slew inputs.

How does the latch enable (LE) pin function in the MAX913EUA-T?

In the MAX913EUA-T, the LE pin controls output transparency: when LE is low, Q and Q̅ follow the IN+/IN− differential voltage in real time; when LE is high or floating, the outputs retain their last valid state until LE returns low. This hardware latch eliminates metastability in sampled-data systems and replaces external flip-flops-critical for synchronized edge detection in PWM controllers and data acquisition.

What is the input common-mode voltage range of the MAX913EUA-T on a +5V supply?

On a +5V single supply (V− = GND), the MAX913EUA-T supports an input common-mode range of –0.2V to +3.5V. This means either input (IN+ or IN−) can safely go 200mV below ground-enabling direct connection to ground-referenced sensors, transformer secondaries, or op-amp outputs that swing slightly negative, without level-shifting circuitry.

Is the MAX913EUA-T pin-compatible with other packages in the MAX913 family?

No-the MAX913EUA-T uses the 8-pin µMAX package (3.05mm × 3.05mm), which has different pinout and footprint than the 8-pin SO (MAX913ESA) or 8-pin PDIP (MAX913EPA). While electrical functionality is identical, PCB layout must match the µMAX outline; migration requires board revision. Always verify land pattern against Maxim's 21-0036 package drawing before layout.
