MAX266BEPI

Overview

The MAX266BEPI+ is a universal active filter IC featuring two independent second-order switched-capacitor filters in a 28-pin PDIP package. It operates on a single supply voltage ranging from 4.74V to 12.6V, or dual supplies of ±2.37V to ±6.3V. The device supports a maximum clock frequency of 140kHz and allows for pin and resistor programming to configure various filter responses. It is designed for precision signal processing applications requiring stable analog filtering capabilities.

Feature Summary

• Dual-channel architecture providing two independent second-order universal active filters within a single integrated circuit
• Switched-capacitor technology enables precise frequency control determined by external clock signals rather than passive components
• Flexible configuration options allow users to program specific filter characteristics through dedicated pin connections and external resistors

Applications

• Precision instrumentation systems requiring selective signal bandpass or lowpass filtering
• Industrial control circuits needing noise rejection and signal conditioning before data conversion
• Communication equipment utilizing active filtering for channel selection or interference suppression

Procurement Notes

Verify the exact ordering suffix to ensure correct packaging and temperature grade specifications. Confirm that the component status aligns with current production requirements, as availability may vary. Cross-reference the manufacturer datasheet for detailed electrical characteristics and recommended operating conditions prior to integration into final designs.

Selection Notes

Select this component when dual-channel active filtering is required without discrete op-amp complexity. Ensure the application clock frequency remains within the supported range to maintain filter accuracy. Evaluate the power supply constraints against the specified voltage limits to guarantee proper operation and stability during implementation.

Part Context

This part belongs to Maxim Integrated's family of universal active filters, designed to replace complex discrete RC networks. It simplifies circuit design by integrating multiple filter stages into a compact surface-mount or through-hole package, offering reliable performance for analog signal processing tasks in various electronic systems.

Replacement Considerations

Check for direct cross-references in distributor databases. Verify pin compatibility and electrical parameter equivalence if substituting with other universal active filter ICs. Ensure any alternative maintains the same switching capacitor architecture and programming interface requirements.
