MAX260BCWG+

Overview

The MAX260BCWG+ is a CMOS dual second-order universal switched-capacitor active filter in a 24-pin Wide SOIC package. It supports microprocessor control for precise filter functions including bandpass, lowpass, highpass, notch, and allpass configurations without external components. The device operates on single +5V or ±5V supplies with a center frequency range of 7.5kHz. It features independent Q and f0 programming via a digital interface, utilizing separate clock inputs for each section.

Feature Summary

• Microprocessor programmable interface for independent control of center frequency and Q factor
• Dual second-order sections supporting multiple filter topologies without external components
• Auto-zero circuitry providing superior DC offset and drift specifications compared to other series variants

Applications

• Microprocessor-tuned filters
• Anti-aliasing filters
• Digital signal processing systems
• Adaptive filters
• Phase-locked loops

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinuation status. Confirm RoHS compliance and lead-free packaging specifications against current manufacturing records. Validate the specific BCWG suffix corresponds to the commercial temperature range and Wide SOIC package format required for the design.

Selection Notes

Select this variant over MAX261 or MAX262 when superior DC accuracy and lower offset voltage are critical requirements. Ensure the application center frequency remains within the 7.5kHz limit defined for the MAX260 series. Verify that the available clock frequencies support the desired fCLK/f0 ratio for the targeted Q factor and bandwidth.

Part Context

This component belongs to the MAX260/MAX261/MAX262 family of microprocessor-programmable universal active filters. While sharing the same pinout and interface logic, the MAX260 is distinguished by its auto-zero architecture which optimizes it for low-frequency precision applications where DC stability outweighs the need for higher maximum operating frequencies found in the MAX261 and MAX262 models.

Replacement Considerations

Publicly confirmed substitute part numbers are not available as the MAX260BCWG+ is discontinued.
