Maxim Integrated MAX7408EUA+T Low-Pass Filter

The Maxim Integrated MAX7408EUA+T is a precision, low-power, 8th-order, low-pass filter specifically designed to provide superior filtering performance for a wide range of applications. This compact and efficient component utilizes Maxim's proprietary switched-capacitor technology to deliver a fixed 30kHz cutoff frequency, making it an ideal choice for anti-aliasing or post-DAC filtering in digital audio, data acquisition systems, and various signal processing tasks.

The MAX7408EUA+T comes in a small µMAX-8 package, which is highly advantageous for space-constrained designs, ensuring that it can be easily integrated into even the most size-sensitive applications without sacrificing performance. The device operates from a single +2.7V to +5.5V supply, providing design flexibility and making it suitable for portable and battery-powered devices.

One of the key features of the MAX7408EUA+T is its low power consumption, drawing a mere 2.2mA of supply current. This characteristic is particularly beneficial for extending the battery life of portable devices. Furthermore, the component offers a low output offset of ±1mV and a high degree of signal accuracy with a signal-to-noise ratio of 80dB, ensuring clean and reliable signal processing.

The filter's 8th-order Butterworth characteristic ensures a maximally flat passband response, which is critical for maintaining the integrity of the original signal while attenuating unwanted high-frequency noise. The MAX7408EUA+T is fully integrated, meaning no external components are required for operation, simplifying the design and reducing the overall bill of materials.

With its robust temperature range of -40°C to +85°C, the MAX7408EUA+T is versatile enough to perform reliably in a variety of environmental conditions. Whether used in industrial controls, wireless communication devices, or medical equipment, this low-pass filter from Maxim Integrated is engineered to deliver high-performance filtering in a miniature package.

For designers looking for a reliable and efficient solution to their filtering needs, the Maxim Integrated MAX7408EUA+T offers a combination of performance, size, and power efficiency that is hard to match.
