MAX263ACPI

Overview

The MAX263ACPI is a pin-programmable universal and bandwidth filter manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 10V and draws a maximum supply current of 8mA. The device features a low-pass, high-pass, band-pass, or notch response selectable via external programming pins. It supports a center frequency range from 10Hz to 100kHz with a quality factor (Q) programmability up to 100. The component is housed in an 8-pin PDIP package.

Feature Summary

• Pin-programmable functionality allows selection among low-pass, high-pass, band-pass, and notch filter responses without internal configuration changes.
• Universal filter architecture provides flexibility for various signal processing applications through external component selection.
• Bandwidth and center frequency are adjustable via external resistors and capacitors, enabling customization for specific signal requirements.

Applications

• Audio signal processing and equalization circuits
• Instrumentation and measurement systems requiring selective filtering
• Communication equipment for channel selection and interference rejection

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm that the AC suffix corresponds to the commercial temperature range and PDIP package variant specified in the datasheet. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Ensure compatibility with existing board layout and power supply specifications before procurement.

Selection Notes

Select this component when a versatile, single-chip solution for multiple filter types is required. Consider the operating frequency range and Q-factor limits to ensure the application falls within the device's capabilities. Evaluate the external component values needed for programming to determine space and cost implications. Verify power supply constraints match the 4.5V to 10V operational range.

Part Context

The MAX263 is part of a family including the MAX264, MAX267, and MAX268, which share similar pin-programmable filter architectures but may differ in specific performance characteristics or package options. This series is designed for applications requiring flexible analog filtering solutions in compact form factors.

Replacement Considerations

Check for direct replacements within the MAX26x family such as MAX264, MAX267, or MAX268, ensuring functional equivalence in filter response and electrical parameters. Verify package compatibility if substituting with different variants. Consult updated datasheets for any revisions in performance specifications or recommended operating conditions.
