MAX262BCWG+T

Overview

The MAX262BCWG+T is a microprocessor-programmable universal active filter from the MAX260/MAX261/MAX262 series, manufactured by Analog Devices/Maxim Integrated. It features two second-order switched-capacitor sections housed in a 24-pin Wide SOIC package with an operating temperature range of 0°C to +70°C. The device supports single +5V or ±5V supply operation and provides independent control over center frequency (f0) and quality factor (Q). It extends the f0 range up to 140kHz using lower clock-to-f0 ratios compared to other series members.

Feature Summary

• Microprocessor interface for precise digital control of filter functions
• Independent programming of center frequency and Q for each section
• Supports multiple filter configurations including bandpass, lowpass, highpass, notch, and allpass

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with existing design specifications before procurement. Confirm availability through authorized distributors as stock levels may vary.

Selection Notes

Select this component when a center frequency range extending to 140kHz is required. Compare against MAX260 and MAX261 if different bandwidth or DC accuracy specifications are needed. Verify that the 24-pin Wide SOIC package fits the target PCB layout constraints.

Part Context

This part belongs to the MAX260/MAX261/MAX262 family of CMOS dual second-order universal switched-capacitor active filters. These devices allow microprocessor control of precise filter functions without requiring external components for various configurations.

Replacement Considerations

MAX262ACWG+T offers higher accuracy with a guaranteed 1% clock-to-f0 ratio error compared to the 2% error of the BCWG variant.
