MAX266AEWI

Overview

The MAX266AEWI+ is a pin-programmable universal switched-capacitor active filter manufactured by Analog Devices under the Maxim Integrated brand. It features two independent channels housed in a 28-pin SOIC package. The device operates within a supply voltage range of 4.74 V to 12.6 V and supports a maximum cutoff frequency of 140 kHz. Designed for commercial applications, it functions reliably between 0°C and +70°C. This component allows for flexible configuration of filter characteristics through external programming pins without requiring external resistors or capacitors.

Feature Summary

• Pin-programmable architecture enables versatile filter configurations without external passive components
• Dual-channel design provides independent signal processing capabilities within a single integrated circuit
• Switched-capacitor technology facilitates precise frequency control and stable performance

Applications

• Signal conditioning in communication systems
• Audio processing circuits requiring programmable filtering
• Instrumentation front-ends needing adjustable bandwidth

Procurement Notes

Verify the specific suffix (e.g., +) for lead-free compliance when sourcing. Confirm availability status as this series may be discontinued or restricted. Ensure the supplier provides valid traceability documentation matching the manufacturer's specifications.

Selection Notes

Select this component when dual-channel programmable filtering is required in a compact surface-mount package. Verify that the operating temperature range meets system requirements. Compare against the MAX266BCWI+ variant if industrial temperature ratings are necessary instead of commercial grades.

Part Context

This part belongs to the MAX266B family of universal switched-capacitor filters. It shares functional similarities with other Maxim Integrated programmable filters but offers specific pinout and electrical characteristics tailored for commercial-grade applications. The SOIC-28 package allows for standard PCB mounting techniques.
