MAX264BCPI+

Overview

The MAX264BCPI+ is a pin-programmable universal switched-capacitor active filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two second-order filter sections housed in a 28-pin PDIP package. The device supports center frequencies up to 140 kHz and operates on dual power supplies ranging from ±2.37 V to ±6.3 V, with a typical supply of ±5 V. It functions within an industrial temperature range of -40°C to +85°C. Configuration of filter parameters such as center frequency, Q factor, and operating mode is achieved through external pin connections without requiring microprocessor control.

Feature Summary

• Pin-programmable configuration for center frequency, Q factor, and filter mode
• Dual second-order universal switched-capacitor filter sections
• Supports bandpass, lowpass, highpass, notch, and allpass configurations

Applications

• Signal processing circuits requiring precise analog filtering
• Instrumentation systems utilizing switched-capacitor techniques
• Telecommunications equipment needing programmable bandwidth filters

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes against current datasheets. Ensure storage conditions meet semiconductor handling standards to prevent damage prior to assembly.

Selection Notes

Select this component when dual independent filter sections are required without digital interface complexity. Verify that the maximum center frequency of 140 kHz meets system requirements. Ensure the PCB layout accommodates the 28-pin PDIP footprint and that the available clock signal matches the desired cutoff specifications.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of universal switched-capacitor filters. These devices share similar architectural principles but differ in maximum center frequency capabilities and specific electrical characteristics. The MAX264 variant specifically extends the operational frequency range compared to lower-speed counterparts in the series.

Replacement Considerations

Direct replacements include other members of the MAX263/MAX264/MAX267/MAX268 family, provided their frequency limits and pinouts are compatible. Verify package type consistency between PDIP variants.
