MAX280CPA

Overview

The MAX280CPA is a fifth-order, zero DC error, low-pass active filter IC manufactured by Analog Devices Inc./Maxim Integrated. It utilizes switched-capacitor technology to provide precise filtering without external resistors or capacitors. The device features an 8-pin PDIP package and operates within a temperature range of 0°C to +70°C. It is designed for applications requiring high accuracy and low power consumption in signal conditioning tasks.

Feature Summary

• Fifth-order low-pass filtering capability with zero DC error
• Switched-capacitor architecture eliminating need for external passive components
• Integrated clock generation for simplified system design

Applications

• Precision sensor signal conditioning
• Anti-aliasing filters in data acquisition systems
• Low-frequency noise reduction in instrumentation

Procurement Notes

Verify component authenticity through authorized distributors as the MAX280CPA is listed as obsolete. Confirm pinout compatibility and thermal specifications against original design requirements. Check for lead-free alternatives if RoHS compliance is mandatory for current projects.

Selection Notes

Select this component when a compact, fifth-order low-pass filter with integrated clocking is required. Ensure the operating frequency range aligns with the 20 kHz cutoff specification. Consider power supply constraints and package size limitations during integration into the final assembly.

Part Context

Part of the Maxim Integrated active filter family, the MAX280CPA represents a specialized solution for analog signal processing. It integrates complex filter functions into a single chip, reducing board space and component count compared to discrete RC filter designs.

Replacement Considerations

Direct substitutes include the MAX280CPA+. Verify functional equivalence before replacement.
