Maxim Integrated MAX7411CUA+T - 5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

The MAX7411CUA+T from Maxim Integrated is a highly sophisticated, 5th-order, lowpass, elliptic, switched-capacitor filter that significantly simplifies the design of high-performance signal conditioning circuits. This integrated circuit is designed to operate with a single +5V supply, making it suitable for a wide range of applications in the consumer, medical, industrial, and telecommunications markets.

Encased in a compact 8-pin µMAX package, the MAX7411CUA+T is part of Maxim's MAX7400 series of filters that are preconfigured for a 30kHz cutoff frequency. However, the frequency can be adjusted by the user with external clock signals, offering flexibility in various applications. The device provides a sharp roll-off with an elliptic response which is ideal for rejecting unwanted noise and signals in a system while maintaining a flat passband response.

The filter's switched-capacitor design eliminates the need for external resistors and capacitors, reducing the PCB space required and simplifying the design process. Additionally, the MAX7411CUA+T features a low-power operation with a typical supply current of just 1.5mA, making it an energy-efficient choice for battery-powered devices.

Key features of the MAX7411CUA+T include its clock-tunable cutoff frequency, which allows for easy adjustment and tuning in the field. Its low distortion and high signal-to-noise ratio ensure high-quality signal processing. Moreover, the device's fully differential inputs and outputs provide improved noise rejection and are conducive to driving analog-to-digital converters (ADCs) directly.

Whether you are designing audio equipment, anti-aliasing filters for data acquisition systems, or any other application requiring precise signal conditioning, the MAX7411CUA+T offers a reliable and high-performance solution. Its ease of use, combined with the support and reliability of Maxim Integrated products, makes this filter a top choice for engineers looking to enhance their designs with minimal effort.
