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 independent second-order filter sections housed in a 28-pin plastic dual in-line package (PDIP). The device supports bandpass, lowpass, highpass, notch, and allpass configurations without requiring external components for basic operation. It operates from a single +5V supply with a maximum voltage of 12.6V and minimum of 4.74V. The center frequency range extends up to 140 kHz, controlled via an input clock and a 6-bit program input. Operating temperature ranges from -55°C to +125°C.

Feature Summary

• Pin-programmable control allows configuration of center frequency, Q factor, and filter operating mode through digital inputs.
• Contains two independent second-order filter sections capable of multiple universal filter functions.
• Eliminates the need for external passive components for standard filter configurations.

Applications

• Signal processing circuits requiring precise frequency selection
• Multiplexed data acquisition systems
• Instrumentation requiring programmable filtering

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific ordering suffixes against current datasheets. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this component when dual-channel programmable filtering is required within a 140 kHz bandwidth. Verify that the PDIP-28 package fits the mechanical constraints of the design. Ensure the system provides a stable clock signal compatible with the 6-bit programming interface.

Part Context

This part belongs to the MAX263/MAX264/MAX267/MAX268 family of universal switched-capacitor filters. The MAX264 variant specifically offers a center frequency range up to 140 kHz, distinguishing it from lower-frequency siblings like the MAX263.

Replacement Considerations

Direct substitutes include other members of the MAX26x family such as the MAX263, MAX267, or MAX268, provided their specific frequency ranges and package types match the application requirements.
