MAX262BCWG

Overview

The MAX262BCWG is a CMOS dual second-order universal switched-capacitor active filter in a 24-pin Wide SO package. It supports center frequencies up to 140kHz with ±5V supplies (4.74V to 6.3V range). The device features microprocessor control via A0-A3 address and D0-D1 data inputs, allowing independent programming of Q and f0. It operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Microprocessor-programmable universal filter architecture
• Independent Q and center frequency control per section
• Supports bandpass, lowpass, highpass, notch, and allpass configurations

Applications

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

Procurement Notes

Verify the specific suffix 'BCWG' against current manufacturer documentation to confirm package type and accuracy grade. Confirm availability status as discontinued or obsolete products may require alternative sourcing strategies.

Selection Notes

Select this component for designs requiring precise digital control over filter parameters without external passive components. Ensure the required center frequency does not exceed 140kHz and that the system clock can be provided within the specified limits.

Part Context

This part belongs to the MAX260/MAX261/MAX262 family of microprocessor programmable universal active filters. The MAX262 variant specifically extends the center frequency range to 140kHz by employing lower clock-to-f0 ratios compared to the MAX260 and MAX261.

Replacement Considerations

MAX262ACWG: Commercial grade, 1% accuracy, same package.
