MAX268BEWG+

Overview

The MAX268BEWG+ is a pin-programmable universal and bandpass filter manufactured by Analog Devices Inc./Maxim Integrated. It features two independent second-order filters housed in a 24-pin SOIC package. The device operates on a supply voltage ranging from 4.74V to 12.6V, with a typical operating voltage of 5V. It supports a center or cutoff frequency of 140kHz. The component is designed for surface-mount installation and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Pin-programmable architecture allows configuration of filter characteristics without external components
• Integrates two independent second-order filter channels within a single package
• Supports both universal and bandpass filter topologies

Applications

• Signal conditioning circuits requiring programmable frequency selection
• Bandpass filtering in communication systems
• Universal filtering applications in industrial instrumentation

Procurement Notes

Verify the specific suffix BEWG against official documentation to confirm package type and temperature grade. Confirm current availability status as discontinuance notices may apply to this family. Ensure compliance with RoHS requirements before integration into final assemblies.

Selection Notes

Select this component when dual-channel programmable filtering is required in a compact SOIC footprint. Verify that the 140kHz frequency specification aligns with system bandwidth needs. Check power supply constraints against the 4.74V to 12.6V operational range.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 series of pin-programmable filters. These devices share common architectural features but differ in channel count, frequency ranges, and package options. The MAX268 specifically provides dual-channel functionality optimized for higher frequency applications compared to lower-frequency variants in the same series.
