Maxim Integrated MAX7424EUA Overview

The MAX7424EUA from Maxim Integrated is a highly-efficient, 5th-order, low-pass Elliptic filter that offers an optimal solution for applications requiring a sharp transition from passband to stopband with minimal signal distortion. This integrated circuit is part of Maxim's MAX742x series of switched-capacitor filters which are designed to provide precise filtering characteristics with the convenience of an integrated solution.

Key Features

• Filter Order: The MAX7424EUA is a 5th-order filter, providing a steeper roll-off and better selectivity compared to lower-order filters.
• Operating Frequency: It features a user-adjustable clock frequency that allows for a wide range of cut-off frequencies, making it highly versatile for various signal processing applications.
• Low Power Consumption: Designed for power-sensitive applications, it operates with a low power consumption, which is critical for battery-operated devices.
• Single-Supply Operation: The device can operate from a single +5V supply, simplifying the power supply design.
• Compact Package: The MAX7424EUA comes in an 8-pin µMAX package, which is ideal for space-constrained applications.

Applications

The MAX7424EUA is suitable for a variety of applications, including:

• Anti-aliasing for data acquisition systems
• Audio signal processing
• Communications systems
• Medical instrumentation
• ADC/DAC filtering

Design Flexibility

Designers can take advantage of the MAX7424EUA's flexibility by configuring the external clock to set the desired cut-off frequency. This can be achieved by either using an external clock source or driving the clock input with a microcontroller or a frequency synthesizer. The filter's characteristics are determined by the ratio of the clock frequency to the corner frequency, which can be easily adjusted to meet the specific needs of the application.

Reliability and Performance

Maxim Integrated is known for its commitment to reliability and performance, and the MAX7424EUA is no exception. With its robust design, it ensures consistent performance even in challenging environmental conditions. This makes it a reliable choice for designers looking to integrate a high-quality filter into their system.
