MAX262ACWG

Overview

The MAX262ACWG 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 using lower clock-to-f0 ratios compared to the MAX260/MAX261. The device operates on single +5V or ±5V supplies within a commercial temperature range of 0°C to +70°C. Each section allows independent programming of center frequency via a 6-bit input and Q control with 128 steps. A guaranteed clock-to-f0 ratio accuracy of 1% is provided for the A grade.

Feature Summary

• Microprocessor interface enables precise digital tuning of filter functions without external components
• Independent programming of center frequency and Q factor for each second-order section
• Supports multiple filter configurations including bandpass, lowpass, highpass, notch, and allpass

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 rating. Confirm that the component meets RoHS compliance requirements if applicable to the design. Ensure the supply voltage matches the specified operational limits for the selected grade.

Selection Notes

Select this model when center frequencies up to 140kHz are required. The A grade guarantees a 1% clock-to-f0 ratio error. Verify that the system can provide the necessary clock inputs for both filter sections. Consider the Wide SO package dimensions for PCB layout constraints.

Part Context

This component belongs to the MAX260/MAX261/MAX262 family of microprocessor programmable universal active filters. The MAX262 variant specifically extends the operating frequency range to 140kHz by utilizing lower sampling ratios relative to the MAX260 and MAX261 models.

Replacement Considerations

The MAX262ACNG serves as a direct replacement offering identical electrical specifications but utilizes a Plastic DIP package instead of the Wide SO form factor.
