Analog Devices Inc./Maxim Integrated MAX962ESA+

Overview

The MAX962ESA+ from Maxim Integrated is a dual ultra-high-speed comparator with internal hysteresis, optimized for single +3V or +5V operation. It features 4.5ns propagation delay (5mV overdrive), 5mA supply current per comparator, Beyond-the-Rails™ input range (–0.1V to V_CC + 0.1V), and TTL/CMOS-compatible outputs-used in GPS receivers, high-speed sampling circuits, and line receivers.

For engineers reviewing the MAX962ESA+ datasheet, MAX962ESA+ pinout, MAX962ESA+ application, or MAX962ESA+ equivalent, key selection considerations include dual-channel timing performance, rail-to-rail input capability, output drive strength (±4mA), operating temperature range (–40°C to +85°C), and SO-8 package compatibility with standard PCB layouts.

Technical Context

The MAX962ESA+ implements a current-driven output stage enabling fast slew rates and low static power consumption after transition. Its internal 3.5mV hysteresis eliminates external feedback resistors while preventing oscillation near trip points.

Unlike latch-equipped variants (MAX961/MAX963), the MAX962ESA+ has no latch-enable or shutdown functionality-its two comparators operate independently with fixed TTL/CMOS outputs, and both inputs support common-mode voltages extending 100mV beyond supply rails.

Key Specifications

Pinout & Package

The MAX962ESA+ is housed in an 8-pin SO (Small Outline) package with exposed pad not present; footprint matches JEDEC MS-012AA standard. Pin 1 is marked with a beveled corner or dot.

Equivalent & Alternatives

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

Compared with LMH7322MA/NOPB and ADCMP602BRMZ-REEL, the MAX962ESA+ offers balanced speed (4.5ns), built-in hysteresis, rail-to-rail inputs, and SO-8 compatibility-making it optimal for cost-sensitive, space-constrained dual-threshold detection where external component count must be minimized.

FAQ

What is the maximum operating supply voltage for the MAX962ESA+?

The MAX962ESA+ supports a supply voltage range of +2.7V to +5.5V. Absolute maximum rating is +6V on V_CC relative to GND. Operation above +5.5V risks permanent damage and violates the guaranteed electrical specifications. For reliable long-term use, maintain V_CC within the 2.7V–5.5V range specified in the datasheet, especially under temperature extremes.

Does the MAX962ESA+ include shutdown or latch functionality?

No, the MAX962ESA+ does not include shutdown or latch-enable features. Unlike the MAX961/MAX963, it lacks SHDN and LE pins. Both comparators operate continuously with fixed TTL/CMOS outputs. This simplifies design for always-on dual-threshold applications but precludes power-gating or result-holding functions. The MAX962ESA+ pinout reflects this: Pins 1–8 are strictly INB−, INB+, GND, INA−, INA+, V_CC, QA, QB.

What is the input common-mode voltage range of the MAX962ESA+?

The MAX962ESA+ features a Beyond-the-Rails™ input common-mode range of –0.1V to V_CC + 0.1V. This means either input (INA+/INA− or INB+/INB−) can safely swing 100mV below GND or 100mV above V_CC without damage or false output inversion-provided the other input remains within that same range. This capability eliminates level-shifters in many sensor and communication interface designs.

Can the MAX962ESA+ drive standard TTL or CMOS logic directly?

Yes, the MAX962ESA+ outputs are fully TTL/CMOS-compatible. Each output (QA and QB) can source or sink up to 4mA while maintaining VOH ≥ V_CC – 0.52V and VOL ≤ 0.52V. This meets standard TTL high/low voltage thresholds across the full –40°C to +85°C range and interfaces directly with 74HC, 74AHC, and most FPGA/ASIC I/O banks without external pull-up resistors or level translators.

Is the MAX962ESA+ RoHS-compliant and lead-free?

Yes, the "+" suffix in MAX962ESA+ denotes a lead(Pb)-free and RoHS-compliant package. It uses matte tin plating on the leads and conforms to EU Directive 2011/65/EU. The device is rated for reflow soldering per JEDEC J-STD-020, with peak temperature tolerance up to +260°C. Full compliance documentation, including Sb, Br, Hg, Cd, Pb, and phthalate content, is available in Maxim's (Analog Devices) official material declarations.
