Maxim Integrated MAX7410EUA+ 5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

The MAX7410EUA+ from Maxim Integrated is a highly sophisticated, 5th-order, lowpass, elliptic, switched-capacitor filter that significantly simplifies the design of precision filtering applications. This compact device, available in an 8-pin µMAX package, is designed to operate with a single +5V supply, making it an ideal choice for a wide range of applications in signal processing and communications.

Key Features

• Fixed Frequency: The MAX7410EUA+ offers a fixed cutoff frequency which is factory set, ensuring consistent performance without the need for external components or adjustments.
• Low Power Consumption: With a typical operating current of just 1.5mA and a power-down feature that reduces current consumption to 0.2µA, this filter is well-suited for battery-powered devices.
• High Selectivity: The elliptic transfer function provides excellent selectivity, with a sharp roll-off near the cutoff frequency, making it ideal for applications requiring the rejection of closely spaced unwanted signals.
• On-Chip Clock Oscillator: The inclusion of an on-chip clock oscillator simplifies design by eliminating the need for an external clock source.
• Flexible Clock Options: For applications requiring a different cutoff frequency or tighter control over the filter characteristics, the device can also be driven by an external clock.

Applications

• Data Acquisition Systems
• Digital Signal Processing
• Anti-Aliasing for Data Communications
• Medical Instrumentation
• Audio and Video Signal Processing

The MAX7410EUA+ is engineered to provide high-performance filtering with minimal design effort. Its user-friendly interface and small footprint make it an excellent choice for engineers looking to add precise filtering capabilities to their projects without the overhead of designing discrete filter circuits. Whether you're working on a sophisticated communication system or a simple audio application, the MAX7410EUA+ offers a reliable and efficient solution for your lowpass filter needs.
