Overview

The MAX9034AUD+ is a quad-channel, general-purpose comparator designed for low-power applications operating from a 2.5V to 5.5V single supply. It features a rail-to-rail output stage and an internal 4mV hysteresis to ensure clean switching even with slow-moving input signals. With a low quiescent current of 35uA per comparator, it is optimized for systems where power efficiency and board space are critical.

Why Choose This Part

This device integrates four independent comparators into a compact 14-TSSOP package, reducing component count in multi-channel designs. It eliminates common comparator issues like phase reversal when inputs are overdriven and simplifies design by including internal hysteresis. The 100dB CMRR and PSRR ensure high accuracy and stability across varying power supply and common-mode conditions.

Applications

Battery-Powered Instrumentation
Utilizing the 35uA low quiescent current to extend operating life in portable handheld devices.
Threshold Detectors
Using the internal 4mV hysteresis to provide stable switching for sensor monitoring without external feedback components.
Level Translators
Leveraging the rail-to-rail push-pull output to interface between different logic voltage domains up to 5.5V.
Zero-Crossing Detectors
Providing fast response times with a 228ns propagation delay for AC signal processing and timing recovery.

Getting Started

To evaluate this part, prototype using a TSSOP-14 to DIP adapter on a breadboard or custom PCB. Ensure a 0.1uF ceramic bypass capacitor is placed as close as possible to the VDD pin to maintain high-frequency stability. Since this is a push-pull output device, no external pull-up resistors are required for logic interfacing, provided the load is within the 4mA output current specification.
