Analog Devices Inc./Maxim Integrated MAX9062EUK+T

Overview

The MAX9062EUK+T from Analog Devices is a nanoPower single comparator with internal 0.2V reference, open-drain output, and 5-pin SOT23 package-designed for ultra-low-power, space-constrained battery-operated systems operating down to 1.0V supply voltage. It delivers 700nA max supply current, -40°C to +85°C operation, and 15µs propagation delay, enabling precise threshold detection in portable medical devices and electronic toys.

For engineers reviewing the MAX9062EUK+T datasheet, MAX9062EUK+T pinout, MAX9062EUK+T application, or MAX9062EUK+T equivalent, key selection criteria include its internal 0.2V reference accuracy (±15mV over temperature), input voltage range extending to -0.3V, open-drain output compatibility with mixed-voltage logic, and guaranteed operation at VCC = 1.0V.

Technical Context

The MAX9062EUK+T implements a noninverting-input comparator architecture with an integrated, temperature-compensated 0.2V reference. Its input stage maintains high impedance even when powered down (VCC = 0V), supporting flexible power-gating schemes in energy-harvesting and wake-on-event designs.

It features built-in hysteresis (±0.9mV) for noise immunity and operates across 1.0V–5.5V supply range while maintaining specified DC performance-including 6mV max input offset voltage and 0.23V max VOL at 500µA sink current with VCC = 1.8V.

FAQ

What is the minimum supply voltage required for reliable operation of the MAX9062EUK+T?

The MAX9062EUK+T is fully specified to operate down to VCC = 1.0V across the full –40°C to +85°C temperature range. At this voltage, it maintains 700nA max supply current, 15µs propagation delay, and 0.2V reference accuracy (±15mV). This enables direct integration with aging alkaline or lithium primary cells without intermediate regulation.

Does the MAX9062EUK+T require external components to function as a comparator?

No. The MAX9062EUK+T integrates a precision 0.2V reference and requires only a single external pull-up resistor on the open-drain OUT pin for logic-level translation. No external reference, biasing resistors, or hysteresis networks are needed for basic threshold detection-reducing BOM count and PCB area versus discrete solutions.

How does the MAX9062EUK+T handle input signals below ground?

The MAX9062EUK+T supports an input voltage range of –0.3V to +5.5V, independent of VCC. This allows direct connection of signals such as op-amp outputs, thermocouple interfaces, or fault-detection nodes that swing slightly negative-without clamping diodes or level-shifting circuitry that would increase power or complexity.

Can the MAX9062EUK+T be used in place of the MAX9060EUK+ in an existing design?

No-direct substitution is not recommended. The MAX9060EUK+ uses an external reference (0.9V–5.5V) and has different input polarity and supply architecture. The MAX9062EUK+T uses an internal 0.2V reference and noninverting input. Swapping requires schematic and firmware changes to accommodate fixed reference and polarity inversion.

What is the purpose of the dual GND pins (Pins 2 and 5) on the MAX9062EUK+T?

Pins 2 and 5 are internally connected ground terminals. Their dual placement improves thermal dissipation and reduces ground loop inductance in high-density layouts. In practice, both must be soldered to the same low-impedance ground plane-no separation or star grounding is required or beneficial for this device.
