Analog Devices Inc./Maxim Integrated MAX962EUA+T

Overview

The MAX962EUA+T 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, ±3.5mV input-referred hysteresis, and Beyond-the-Rails™ input common-mode range extending 100mV beyond both rails. It is used in GPS receivers and high-speed sampling circuits where precise, noise-immune threshold detection is required.

For engineers reviewing the MAX962EUA+T datasheet, MAX962EUA+T pinout, MAX962EUA+T application, or MAX962EUA+T equivalent, key selection considerations include propagation delay vs. overdrive, rail-to-rail input capability, output drive strength (4mA to within 0.52V of rails), shutdown current (not supported on MAX962), and μMAX® package thermal performance (330mW at +70°C).

Technical Context

The MAX962EUA+T implements a current-driven output stage enabling fast slew rates and low static power after transition. Its internal 3.5mV hysteresis eliminates external feedback resistors and prevents oscillation near trip points without requiring latch-enable logic.

Unlike MAX961/MAX963, it lacks shutdown and latch-enable functionality. It uses a differential input stage with front-to-back diode protection (±3×VF) and 200Ω series resistors, supporting robust operation under large differential inputs while maintaining 8kΩ differential and 130kΩ common-mode input impedance.

Key Specifications

Pinout & Package

The MAX962EUA+T is housed in an 8-pin μMAX® package (package code U8-1), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal enhancement. This RoHS-compliant lead-free package supports high-density PCB layouts and offers improved thermal resistance (4.10mW/°C derating above +70°C).

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in precision analog, mixed-signal, and high-speed interface ICs for industrial, communications, and consumer applications.

The MAX961–MAX964/MAX997/MAX999 product line was designed specifically for ultra-high-speed, low-power, single-supply comparator applications in portable and signal-integrity-critical systems such as GPS, test equipment, and high-speed data acquisition.

FAQ

What is the operating temperature range for the MAX962EUA+T?

The MAX962EUA+T is specified for operation from -40°C to +85°C (E grade). This industrial temperature range is guaranteed across all electrical parameters in the datasheet, including propagation delay, input offset voltage, and supply current. The μMAX® package's thermal characteristics support reliable operation at the upper limit when mounted on a PCB with adequate copper pour and decoupling.

Does the MAX962EUA+T support shutdown mode?

No, the MAX962EUA+T does not include a shutdown feature. Shutdown is available only on MAX961, MAX963, MAX964, and MAX997 variants (pin 8 = SHDN). The MAX962EUA+T has no dedicated shutdown pin and draws 5mA per comparator continuously under normal operation. For low-power alternatives with shutdown, consider the MAX997EUA+T.

What is the input common-mode voltage range of the MAX962EUA+T?

The MAX962EUA+T features a Beyond-the-Rails™ input common-mode range of -0.1V to VCC + 0.1V. This means either input (INA+, INA−, INB+, INB−) can be driven 100mV below GND or 100mV above VCC without causing false output inversion or damage, provided the other input remains within this same range. This eliminates level-shifting requirements in many sensor and communication interface applications.

Can the MAX962EUA+T drive standard TTL or CMOS logic directly?

Yes, the MAX962EUA+T outputs are TTL/CMOS-compatible. Each output (QA and QB) can source or sink 4mA while maintaining VOH ≥ VCC − 0.52V and VOL ≤ 0.52V, meeting standard TTL voltage thresholds. No external pull-up resistors are required, and the outputs interface directly with 3.3V or 5V logic families without level translation.

What package type is used for the MAX962EUA+T and what are its key mechanical features?

The MAX962EUA+T uses the 8-pin μMAX® package (U8-1), a surface-mount package measuring 3mm × 3mm × 0.8mm with an exposed thermal pad. It is RoHS-compliant (+ suffix), has a land pattern defined in Maxim document 90-0092, and provides 330mW power dissipation at +70°C with 4.10mW/°C derating above that temperature. Its compact size supports high-density routing in portable electronics.
