The MAX7403ESA+ is a high-performance, 8th-order, lowpass, elliptic, switched-capacitor filter that significantly reduces the footprint and design complexity of implementing precision filtering solutions. Designed and manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this filter is optimized for applications requiring a sharp roll-off and low ripple in both the passband and stopband.

Key Features

• High-Order Filter: The 8th-order elliptic response ensures exceptional filter characteristics with a sharp transition band.
• Fixed Frequency: The MAX7403ESA+ operates at a fixed clock frequency that is 100 times the corner frequency.
• Low Distortion: It offers low signal distortion, making it ideal for precision filtering tasks.
• Easy Integration: The filter’s small 8-pin SO package simplifies integration into a variety of designs.
• Single-Supply Operation: It operates from a single +5V supply, reducing power supply requirements.
• Clock-Tunable Corner Frequency: The corner frequency can be tuned by adjusting the clock frequency, providing design flexibility.
