MAX262AEWG

Overview

The MAX262AEWG is a CMOS dual second-order universal switched-capacitor active filter in a 24-pin Wide SOIC package. It provides microprocessor control over precise filter functions, including bandpass, lowpass, highpass, notch, and allpass configurations without external components. The device features two independent filter sections with center frequency (f0) and Q programmed via a 6-bit input and separate Q control. Operating from single +5V or ±5V supplies, the MAX262 extends the center frequency range to 140kHz using lower clock-to-f0 ratios compared to other variants.

Feature Summary

• Microprocessor interface for independent f0 and Q programming
• Universal filter configuration support without external components
• Guaranteed 1% clock-to-f0 ratio accuracy for A grade devices

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure supply voltage requirements match the design specifications. Confirm lead-free status if required by project constraints. Cross-reference pinout details with the datasheet before integration.

Selection Notes

Select this component when higher center frequencies up to 140kHz are required. The A grade ensures tighter clock-to-f0 ratio accuracy. Consider the Wide SOIC package for surface-mount applications. Verify that the microprocessor interface timing meets system requirements.

Part Context

Part of the MAX260/MAX261/MAX262 family of microprocessor programmable universal active filters. The MAX262 variant specifically targets higher frequency applications through optimized sampling ratios. Available in commercial, extended, and military temperature ranges across DIP and SOIC packages.

Replacement Considerations

MAX260AEWG offers superior DC offset performance but lower maximum center frequency. MAX261AEWG provides intermediate frequency capabilities. Verify pin compatibility and software code adjustments when substituting within the series.
