MAX262AENG+

Overview

The MAX262AENG+ is a microprocessor-programmable universal active filter featuring two second-order switched-capacitor sections in a 24-pin Plastic DIP package. It operates on single +5V or ±5V supplies with an extended temperature range of -40°C to +85°C. The device supports center frequencies up to 140kHz using lower clock-to-f0 ratios, providing 64-step f0 control and 128-step Q control via a digital interface.

Feature Summary

• Microprocessor-controlled programming for precise filter functions
• Dual second-order sections supporting bandpass, lowpass, highpass, notch, and allpass configurations
• Independent control of center frequency and quality factor

Applications

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

Procurement Notes

Verify the specific suffix 'ENG+' against current manufacturer documentation to confirm the exact package type and temperature rating. Ensure compatibility with existing PCB footprints for the 24-pin DIP configuration before finalizing procurement orders.

Selection Notes

Select this component when designing programmable filters requiring independent control over center frequency and Q. Verify that the required operating frequency does not exceed 140kHz and that the system can provide the necessary clock signals for the switched-capacitor architecture.

Part Context

This part belongs to the MAX260/MAX261/MAX262 family of CMOS dual second-order universal switched-capacitor 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 models.
