MAX264BEPI+

Overview

The MAX264BEPI+ is a pin-programmable universal and bandwidth active filter manufactured by Analog Devices Inc./Maxim Integrated. It utilizes switched-capacitor technology to provide flexible filtering capabilities within a single integrated circuit. The device operates on dual power supplies ranging from ±2.37V to ±6.3V, with a typical nominal supply of ±5V. It is housed in a 28-pin Plastic Dual In-Line Package (PDIP) designed for through-hole mounting. The component supports a center frequency or cutoff frequency up to 140 kHz and features two functional channels. Key electrical characteristics include a maximum power dissipation of 730.8 mg equivalent weight impact, operating temperature range from 0°C to +70°C, and a standard tube packaging format.

Feature Summary

• Pin-programmable architecture allows configuration as either a universal or bandpass filter without external component changes.
• Switched-capacitor design enables precise frequency control determined solely by an external clock signal.
• Dual-channel functionality provides two independent filter sections within a single package.

Applications

• Signal conditioning circuits requiring programmable frequency response
• Industrial process control systems utilizing analog signal filtering
• Communication equipment needing adjustable bandwidth selection

Procurement Notes

Verify the specific suffix 'BEPI+' against official manufacturer documentation to confirm the exact temperature grade and package variant. Ensure compatibility with existing PCB footprints for the 28-pin PDIP configuration. Confirm availability status directly with authorized distributors as lead times may vary. Validate that the required clock frequency aligns with the device's operational limits before finalizing procurement orders.

Selection Notes

Select this component when a versatile, pin-configurable active filter is required for applications up to 140 kHz. Ensure the system design accommodates the necessary dual power supply rails within the specified voltage range. Consider the PDIP package constraints if space limitations favor surface-mount alternatives like the SOIC variant. Verify that the external clock source meets the stability requirements for accurate filter performance.

Part Context

The MAX264BEPI+ belongs to the MAX263/MAX264/MAX267/MAX268 family of pin-programmable filters. This series shares common switched-capacitor architecture but differs in specific channel counts and configuration options. The BEPI+ designation indicates a specific commercial grade version in a PDIP package, distinct from industrial or wide-temperature variants found in other suffixes within the same product line.

Replacement Considerations

Direct substitutes include other members of the MAX26x family such as the MAX263, MAX267, or MAX268, provided their specific channel counts and pin configurations match the design requirements. Surface-mount equivalents like the MAX264BCWI+ offer identical functionality in a different package type. Always verify pinout compatibility and electrical specifications before substituting.
