Introducing the MAX291EPA+ from Maxim Integrated

The MAX291EPA+ is a high-performance, 8th-order, lowpass, switched-capacitor filter that is designed to provide sharp cutoff characteristics and excellent frequency response. This precision filter from Maxim Integrated is a versatile component suitable for a wide range of signal processing applications where noise reduction and signal conditioning are critical.

With its easy-to-use interface, the MAX291EPA+ can be configured for a variety of cutoff frequencies without the need for external components, making it an ideal choice for compact and efficient designs. The device operates from a single +5V supply, providing a convenient solution for systems with limited power options. Its 8th-order Butterworth characteristic ensures a maximally flat passband, which is essential for preserving the integrity of the filtered signal.

The MAX291EPA+ offers a clock-to-cutoff frequency ratio that is pre-set to 100:1, allowing for straightforward frequency adjustment through an external clock. Additionally, the filter's low THD (Total Harmonic Distortion) and high dynamic range make it suitable for high-fidelity audio applications, as well as for data acquisition and communication systems where signal integrity is paramount.

Key features of the MAX291EPA+ include:

• 8th-order lowpass Butterworth filter characteristic
• Single +5V supply operation
• No external components required for tuning
• User-adjustable cutoff frequency via external clock
• Low THD and high signal-to-noise ratio
• Compact 8-pin DIP or SO package options

Whether you are designing audio equipment, anti-aliasing filters for data acquisition systems, or any other application requiring precise analog filtering, the MAX291EPA+ is an excellent choice. Its reliable performance, ease of use, and integration-friendly design make it a go-to component for engineers looking to enhance their signal processing capabilities.

Maxim Integrated continues to provide innovative, high-quality solutions for the electronics industry, and the MAX291EPA+ is yet another example of their commitment to excellence in integrated circuit design.
