Analog Devices Inc./Maxim Integrated MAX9013ESA+

Overview

MAX9013ESA+ from Maxim Integrated is a single, high-speed, precision TTL comparator with complementary outputs and latch enable functionality, operating from a 4.5V–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 circuits.

For engineers reviewing the MAX9013ESA+ datasheet, MAX9013ESA+ pinout, MAX9013ESA+ application, or MAX9013ESA+ equivalent, key selection considerations include its latch-enabled single-supply operation, complementary TTL outputs, guaranteed –0.2V to (VCC – 1.9V) common-mode input range, and compatibility with space-constrained SO-8 layouts.

Technical Context

The MAX9013ESA+ employs a fully differential bipolar input stage with no built-in hysteresis, enabling high-resolution comparison without resolution loss. Its latch function (LE pin) allows synchronous capture of comparator state, with 2ns setup and 0.5ns hold time, and 5ns latch propagation delay.

It features stable linear-region behavior - eliminating oscillation even with near-zero differential input slew rates - and supports input voltages down to –0.2V (200mV below ground) without output phase reversal. The complementary outputs (OUT/OUTB) provide matched rise/fall times (3ns/2ns) into 5pF loads.

FAQ

What is the maximum input overdrive voltage supported by the MAX9013ESA+ without damage?

The MAX9013ESA+ supports input voltages from –0.3V to (VCC + 0.3V) without permanent damage. While the specified common-mode range is –0.2V to (VCC – 1.9V), either input can safely reach these absolute limits. Operation outside the common-mode range yields indeterminate output states, but the device remains unharmed. This robustness allows safe interfacing with transient-prone sensor outputs or mismatched signal sources.

Does the MAX9013ESA+ require external hysteresis for stable operation?

No, the MAX9013ESA+ does not require external hysteresis. Its internal architecture prevents oscillation in the linear region, even with near-zero input slew rates or low overdrive (e.g., 5mV). Adding hysteresis would degrade resolution without benefit. The MAX9013ESA+ achieves stable, high-fidelity comparisons across its full input range - a key differentiator versus conventional high-speed comparators.

How does the latch enable (LE) pin function on the MAX9013ESA+?

When LE is low (≤0.8V), the MAX9013ESA+ operates transparently: OUT and OUTB respond immediately to IN+/IN–. When LE is high (≥2V), the current output state is latched and held regardless of subsequent input changes. The latch has 2ns setup time and 0.5ns hold time, with 5ns propagation delay from LE deassertion to output update - enabling precise synchronous sampling in data acquisition systems.

Can the MAX9013ESA+ operate from a 3.3V supply?

No, the MAX9013ESA+ is specified only for 4.5V to 5.5V single-supply operation. Its TTL-compatible outputs, internal biasing, and propagation delay performance are guaranteed within this range. At 3.3V, VOH drops below TTL high-level minimum (2.4V), VOL rises above TTL low-level maximum (0.6V), and propagation delay increases significantly. For 3.3V systems, consider the MAX961 series or similar 3V-optimized comparators.

What is the purpose of the N.C. pin (Pin 8) on the MAX9013ESA+?

Pin 8 is a no-connect terminal with no internal bonding. Though electrically inactive, Maxim recommends tying it to GND to improve electromagnetic interference (EMI) immunity and stabilize the package's thermal and mechanical behavior. Leaving Pin 8 floating may increase susceptibility to noise coupling in high-frequency layouts - a best practice confirmed in Maxim's board layout guidelines for the MAX9013ESA+.
