Analog Devices Inc./Maxim Integrated MAX962ESA+T

Overview

MAX962ESA+T from Maxim Integrated is a dual ultra-high-speed comparator optimized for single +3V or +5V operation, featuring 4.5ns propagation delay (5mV overdrive), 5mA supply current per comparator, and Beyond-the-Rails™ input range extending ±100mV beyond VCC/GND. It operates in industrial temperature range (–40°C to +85°C) and targets high-speed threshold detection in GPS receivers and line receivers.

For engineers reviewing the MAX962ESA+T datasheet, MAX962ESA+T pinout, MAX962ESA+T application, or MAX962ESA+T equivalent, key selection criteria include propagation delay skew (<0.3ns between channels), rail-to-rail output drive capability (±4mA to within 0.52V of rails), internal 3.5mV hysteresis for noise immunity, and SO-8 package compatibility with standard PCB layouts.

Technical Context

The MAX962ESA+T implements a current-driven output stage enabling fast slew rates while maintaining TTL/CMOS-compatible logic levels. Its differential input stage includes integrated front-to-back diode clamps and 200Ω series resistors, limiting differential input voltage to ≤2.1V and supporting robust ESD protection without external components.

No shutdown or latch-enable functionality is present - unlike MAX961/MAX963/MAX964/MAX997 - confirming its role as a dedicated dual comparator with fixed timing behavior and no control logic overhead. Input common-mode rejection (CMRR) is specified at 0.1–0.5 mV/V, and power-supply rejection (PSRR) at 0.05–0.3 mV/V across the operating voltage range.

FAQ

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

The MAX962ESA+T supports a supply voltage range of 2.7V to 5.5V. Absolute maximum rating is –0.3V to +6V on VCC relative to GND. Operation beyond 5.5V risks permanent damage and violates the guaranteed electrical specifications. All published performance data-including propagation delay, hysteresis, and output swing-is validated only within the 2.7V–5.5V range. Exceeding this range invalidates parametric guarantees for MAX962ESA+T.

Does MAX962ESA+T support shutdown mode?

No, MAX962ESA+T does not include shutdown functionality. Unlike MAX961/MAX963/MAX964/MAX997, which feature a SHDN pin and consume only 270μA in shutdown, the MAX962ESA+T lacks both the SHDN terminal and internal shutdown circuitry. Its quiescent supply current remains fixed at ~5mA per comparator across the full operating temperature range. This reflects its design focus on deterministic, always-on high-speed comparison without control logic overhead.

What is the input hysteresis value for MAX962ESA+T and how is it implemented?

MAX962ESA+T provides a fixed internal hysteresis of 3.5mV, measured as the difference between rising- and falling-input trip points. This hysteresis is implemented via on-chip feedback circuitry-not external resistors-ensuring consistent noise immunity across temperature and process variations. It eliminates the need for external hysteresis networks, simplifies PCB layout, and maintains stable switching behavior even with slow-moving or noisy input signals. The 3.5mV value is guaranteed across the full –40°C to +85°C range for MAX962ESA+T.

Can MAX962ESA+T accept input voltages below ground or above VCC?

Yes, MAX962ESA+T supports 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 false output inversion-provided the other input remains within that same range. This capability enables direct interfacing with AC-coupled signals, sensor outputs with negative offsets, or overshoot/undershoot transients without external level-shifting circuitry. It is a core differentiator of MAX962ESA+T versus standard comparators.

What package type and RoHS status does MAX962ESA+T use?

MAX962ESA+T uses an 8-pin SO (Small Outline) package with industry-standard footprint S8-2 and land pattern 90-0096. The "+" suffix in the part number confirms it is lead(Pb)-free and RoHS-compliant. The package has no exposed thermal pad and is rated for surface-mount reflow assembly. Pin 1 is marked with a beveled corner or dot, and the device is specified for operation from –40°C to +85°C ambient temperature. This SO-8 variant is pin-compatible with other members of the MAX96x family in the same package, such as MAX961ESA and MAX997ESA.
