MAX268BCWG+T

Overview

The MAX268BCWG+T 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 typical operation at ±5V. The device features two independent filter sections housed in a 28-lead Thin Small Outline Package (TSOP) with a .300-inch width. Key electrical parameters include a center frequency or cutoff frequency range from 0.0004 kHz to 57 kHz, an operating temperature range of -40°C to +85°C, and a maximum negative supply voltage of -6.3V.

Feature Summary

• Pin-programmable architecture allows configuration of filter characteristics without external components.
• Contains two independent universal filter sections for versatile signal processing applications.

Applications

• Frequency division multiplexing systems
• Telemetry channel selection
• Data acquisition front-end filtering

Procurement Notes

Verify the specific suffix 'BCWG+T' against official Analog Devices documentation to confirm package type, temperature grade, and tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints for the 28-lead TSOP variant before procurement.

Selection Notes

Select this component when dual universal filters are required in a surface-mount format. Confirm that the pin-programmable frequency range meets the application's spectral requirements. Verify power supply constraints align with the specified 4.75V to 12.6V operational window.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of pin-programmable universal and bandwidth filters. These devices share common architectural features but differ in package options and specific performance variations. The MAX268 variant specifically offers dual filter sections in compact packages including SOIC and TSOP.

Replacement Considerations

Direct replacements within the same family include MAX263, MAX264, and MAX267 variants. Verify pinout compatibility and package dimensions (TSOP vs. PDIP/SOIC) before substitution. Cross-reference specific suffix codes for temperature and packaging differences.
