MAX268BCNG

Overview

The MAX268BCNG is a pin-programmable universal and bandwidth filter IC manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.75V to 12.6V, with a typical operating voltage of 5V. The device features two independent filter channels housed in a 20-pin SOIC package (0.300 inch width). It supports center frequencies ranging from 0.0004 kHz to 100 kHz and offers programmable quality factors up to 100. The component functions as an active switched-capacitor filter suitable for precision signal processing applications.

Feature Summary

• Pin-programmable architecture allows configuration of center frequency and quality factor without external components
• Dual-channel design provides two independent universal filters within a single integrated circuit
• Supports wide dynamic range operation with low distortion characteristics

Applications

• Instrumentation signal conditioning
• Data acquisition systems
• Medical instrumentation front-ends

Procurement Notes

Verify the specific suffix BCNG against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 20-pin SOIC format. Confirm that the manufacturing source matches the specified brand requirements for critical implementations.

Selection Notes

Select this component when dual universal filters are required in a compact surface-mount package. Evaluate the maximum center frequency and Q-factor requirements against the application needs. Consider the supply voltage constraints and ensure the system power rails align with the specified operational range.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of pin-programmable universal and bandwidth filters. These devices share similar internal architectures but differ in package options and specific performance characteristics. The MAX268 variant specifically utilizes the 20-pin SOIC form factor for space-constrained designs.

Replacement Considerations

MAX268BCN is a PDIP alternative offering identical electrical specifications in a through-hole package.
