MAX262ACNG

Overview

The MAX262ACNG is a CMOS dual second-order universal switched-capacitor active filter in a 24-pin Plastic DIP 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 factor, with a guaranteed clock-to-f0 ratio accuracy of 1% for the A grade.

Feature Summary

• Microprocessor programmable interface for precise control of filter functions
• Independent digital programming of center frequency and Q factor
• Supports multiple 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 component authenticity through authorized distributors or manufacturer channels. Confirm the specific ordering suffix matches the required package type and temperature rating. Check for obsolescence status as this part may be discontinued. Ensure supply chain documentation aligns with current manufacturing standards.

Selection Notes

Select the MAX262ACNG when center frequencies up to 140kHz are required. Choose this variant over the MAX260 or MAX261 if higher bandwidth is necessary. Verify that the application environment falls within the 0°C to +70°C commercial temperature range. Ensure the design accommodates the 24-pin PDIP footprint.

Part Context

This component belongs to the MAX260/MAX261/MAX262 family of microprocessor-programmable universal active filters. The MAX262 specifically extends the operating range to 140kHz by utilizing lower sampling ratios. It shares the same pinout and interface logic as its siblings but differs in internal oscillator scaling.

Replacement Considerations

The MAX262AENG serves as a direct replacement offering an extended temperature range of -40°C to +85°C. The MAX262AEWG+ provides the same electrical performance in a Wide SOIC-24 surface-mount package.
