Maxim Integrated MAX297CWE+T: High-Performance, 8th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

The MAX297CWE+T from Maxim Integrated is a state-of-the-art, 8th-order, lowpass, elliptic filter that offers a unique combination of features and performance for signal processing applications. Designed using switched-capacitor technology, this filter component provides a precise filtering solution with a sharp transition band and excellent stopband attenuation.

Key Features:

• High Order Filter: As an 8th-order filter, the MAX297CWE+T provides a steep attenuation curve, making it ideal for applications requiring a sharp cutoff between the passband and the stopband.
• Elliptic Response: The elliptic filter response ensures maximum selectivity and fast transition from passband to stopband, which is critical for applications where space and frequency are limited.
• Programmable Corner Frequency: The corner frequency can be set from 0.1Hz to 25kHz, providing flexibility for a wide range of applications. The frequency can be adjusted using external clock signals or resistors.
• Low Distortion: With low total harmonic distortion (THD), the MAX297CWE+T is suitable for high-fidelity audio applications and other signal processing tasks that require clean filtering with minimal signal alteration.
• Single or Dual Power Supply: This filter can operate with a single +5V power supply or dual ±5V supplies, allowing for easy integration into various system architectures.

Applications:

The versatility of the MAX297CWE+T makes it an excellent choice for a broad range of applications. It is particularly well-suited for:

• Anti-aliasing for data acquisition systems
• Digital signal processing interfaces
• High-fidelity audio equipment
• Instrumentation and control systems
• Communication devices

The MAX297CWE+T comes in a compact 16-pin SOIC package, making it suitable for space-constrained designs without compromising performance. With its robust design and high-quality filtering capabilities, the MAX297CWE+T from Maxim Integrated is an ideal choice for engineers and designers looking for a reliable and flexible solution to their filtering needs.
