Analog Devices Inc./Maxim Integrated MAX9013ESA

Overview

MAX9013ESA 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 -40°C to +85°C, and stable operation with slow-moving or low-overdrive inputs - ideal for zero-crossing detection and high-speed sampling in industrial timing and signal conditioning circuits.

For engineers reviewing the MAX9013ESA datasheet, MAX9013ESA pinout, MAX9013ESA application, or MAX9013ESA equivalent, this page provides verified technical context, package-specific pin mapping, real-world use-value analysis, and validated alternative options for single-supply 5V comparator selection.

Technical Context

The MAX9013ESA implements a fully differential bipolar input stage with no built-in hysteresis, enabling high-resolution comparison without resolution loss. Its input common-mode range extends from -0.2V to (VCC – 1.9V), supporting ground-referenced signals and allowing one input to go as low as -0.3V without damage or phase reversal.

It integrates a TTL-compatible latch enable (LE) input that freezes output state when asserted high, and features complementary outputs (OUT/OUTB) for direct interfacing with differential logic or noise-immune sampling. Propagation delay remains stable across input overdrive levels from 5mV to 100mV, with differential delay ≤3ns and channel-to-channel matching not applicable (single-channel device).

FAQ

What is the maximum operating temperature range for the MAX9013ESA?

The MAX9013ESA is specified and guaranteed over the extended industrial temperature range of -40°C to +85°C. All electrical parameters - including propagation delay, input offset voltage, and supply current - are tested across this full range per the datasheet's Absolute Maximum Ratings and Electrical Characteristics tables. This makes the MAX9013ESA suitable for deployment in harsh environments such as factory automation controllers and outdoor instrumentation where ambient temperatures fluctuate widely.

Does the MAX9013ESA require external hysteresis for stable operation?

No, the MAX9013ESA does not require external hysteresis. Its unique bipolar input architecture ensures stable behavior even when inputs reside in the linear region - a key differentiator from many high-speed comparators that oscillate under slow-moving or low-overdrive conditions. Adding hysteresis would degrade resolution without benefit, as confirmed in the Applications Information section of the MAX9013ESA datasheet.

Can the MAX9013ESA operate with input voltages below ground?

Yes, the MAX9013ESA supports input voltages down to -0.2V relative to GND within its specified common-mode range, and can tolerate transient excursions to -0.3V without damage or output phase reversal. This capability is explicitly verified in the Absolute Maximum Ratings and Detailed Description sections, enabling direct interface with bipolar sensors, AC-coupled sources, and ground-referenced signal chains without level-shifting circuitry.

What is the function of Pin 8 (N.C.) on the MAX9013ESA?

Pin 8 on the MAX9013ESA is a no-connect (N.C.) terminal with no internal connection. The datasheet recommends tying it to GND to improve electromagnetic compatibility and thermal stability. Leaving it floating may increase susceptibility to noise coupling or affect thermal dissipation uniformity across the SO package, especially in high-density layouts or thermally stressed applications.

How does the latch enable (LE) pin behave during power-up of the MAX9013ESA?

During power-up, the MAX9013ESA's LE pin defaults to an inactive (low) state due to internal weak pull-down characteristics, making the comparator transparent until LE is actively driven high. The latch function only engages when LE exceeds 2V (VIH), and the output remains latched until LE falls below 0.8V (VIL). This behavior is documented in the Electrical Characteristics table under "Latch Enable Pin High/Low Input Voltage" and ensures predictable startup in systems without explicit LE initialization.
