Key Features

  • Quad comparator with 12 µs response time operates from a single +2.5 V to +11 V supply, enabling versatile threshold detection across 3.3 V and 5 V logic systems
  • CMOS/TTL compatible open-drain outputs allow direct interfacing with microcontrollers, logic gates, and bus architectures without level-shifting circuitry
  • Wide supply voltage range of +2.5 V to +11 V single supply or ±5.5 V dual supply covers both low-power battery applications and industrial 5 V/9 V systems
  • 16-pin SOIC (SO-16) package with four independent comparator channels reduces component count and PCB area versus four discrete comparator ICs

Applications

The MAX934ESE+ is used in battery-powered systems for voltage monitoring, window comparator circuits, and zero-crossing detection where low power consumption and 2.5 V to 11 V supply flexibility are required. In industrial equipment, its four independent comparator channels simultaneously monitor multiple analog thresholds for over-voltage, under-voltage, and current-limit protection in power management circuits. The CMOS output structure and 12 µs propagation delay also make it suitable for PWM signal conditioning and analog-to-digital level conversion in embedded microcontroller designs.

Frequently Asked Questions

What is the supply voltage range and response time of MAX934ESE+?

The MAX934ESE+ operates from a single supply of +2.5 V to +11 V, or a dual supply of ±1.25 V to ±5.5 V, with a typical comparator response time of 12 µs. This combination makes it suitable for battery-operated devices from 3 V coin cells up to 9 V industrial systems requiring threshold detection.

How many comparator channels does the MAX934ESE+ provide and what logic families do the outputs support?

The MAX934ESE+ contains 4 independent comparator channels in a single 16-pin SOIC package, with open-drain CMOS/TTL compatible outputs. Each channel can drive TTL loads at 5 V or CMOS logic at 3.3 V directly without external level-shifting, allowing 4 simultaneous threshold comparisons on one IC.

For a 3.3 V battery-powered IoT sensor, how suitable is MAX934ESE+ for voltage threshold monitoring?

At 3.3 V single supply within its +2.5 V to +11 V operating range, MAX934ESE+ is well suited for IoT sensor voltage monitoring. Its CMOS outputs interface directly with 3.3 V microcontrollers, enabling over-voltage and under-voltage detection at programmable thresholds set by resistor dividers with no additional interface components.

When is MAX934ESE+ preferred over LM339 for quad comparator applications?

MAX934ESE+ is preferred over LM339 when single-supply operation below 5 V is required, since MAX934ESE+ operates down to 2.5 V single supply versus LM339's 2 V minimum (±1 V dual). Additionally, MAX934ESE+ offers CMOS-compatible outputs and 12 µs response time making it faster and more compatible with 3.3 V systems than the standard LM339.
