MAX265BCPI+

Overview

The MAX265BCPI+ is a universal active filter IC from Maxim Integrated, manufactured by Analog Devices. It utilizes switched-capacitor technology to implement two independent second-order filters within a single package. The device supports a cutoff or center frequency of 57kHz and offers 2% accuracy. It operates on a single supply voltage and features a 28-pin Plastic DIP (0.600 inch) package with an extended industrial temperature range.

Feature Summary

• Universal switched-capacitor architecture allows flexible filter configuration
• Integrates two independent second-order filter sections
• Pin and resistor programmable for customized frequency response

Applications

• Signal conditioning in data acquisition systems
• Anti-aliasing filtering for analog-to-digital converters
• Voice messaging and audio processing circuits

Procurement Notes

Verify the component status carefully as some sources indicate this specific part number may be obsolete. Confirm the manufacturer source is Analog Devices Inc. or Maxim Integrated. Ensure the package type matches the required 28-pin DIP specification. Check for RoHS compliance markings if environmental standards are mandatory for your assembly process.

Selection Notes

Select this component when a compact solution for dual second-order filtering is required without external op-amps. The switched-capacitor design necessitates a clock signal input, so ensure system timing resources are available. Consider the 57kHz frequency limit and 2% accuracy tolerance against application requirements before choosing over discrete implementations.

Part Context

This part belongs to the MAX265 series of universal active filters. These devices were designed to replace complex discrete RC networks with integrated switched-capacitor solutions. The BCPI suffix denotes the commercial temperature grade and plastic DIP packaging format common in legacy industrial electronics.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Due to the potential obsolete status of this specific variant, consult official Analog Devices channels for current equivalent recommendations or direct replacements.
