The MAX7400EPA from Maxim Integrated is a high-performance, 8th-order, lowpass, elliptic, switched-capacitor filter that significantly reduces the complexity of signal conditioning in data acquisition systems. This precision filter component is designed to provide a sharp cutoff characteristic, making it an ideal choice for applications requiring a stringent filter specification with a fast roll-off and minimal signal distortion.

Key Features

• High Order Filter: The 8th-order elliptic response ensures excellent selectivity with a fast roll-off and minimal passband ripple.
• Fixed Frequency: The MAX7400EPA operates at a fixed clock frequency that is 100 times the cutoff frequency, simplifying the design process by eliminating external components for frequency setting.
• Low Power Consumption: With a typical operating current of just 2mA and the ability to run from a single +5V supply, this filter is an energy-efficient solution for portable and battery-powered applications.
• No External Components Required: Unlike traditional continuous-time filters, the MAX7400EPA does not require any external resistors or capacitors, which saves board space and reduces system complexity.
• Easy to Use: This filter is designed to be user-friendly with a simple clock input interface, making it easy to integrate into a wide range of electronic systems.

Applications

The MAX7400EPA is versatile and can be used in a variety of applications where signal integrity and precision are crucial. Common applications include:

• Anti-aliasing for data acquisition systems
• Signal conditioning in communication systems
