MAX262BENG+

Overview

The MAX262BENG+ is a microprocessor-programmable universal active filter featuring two second-order switched-capacitor sections. It supports bandpass, lowpass, highpass, notch, and allpass configurations without external components. The device allows independent programming of center frequency (f0) via a 6-bit input and Q factor via a separate control word. Operating with ±5V supplies, it achieves a maximum clock frequency of 4MHz and extends the center frequency range up to 140kHz using lower clock-to-f0 ratios. It is housed in a 24-pin Plastic DIP package.

Feature Summary

• Microprocessor interface enables precise digital control over filter functions
• Dual second-order sections allow complex filter polynomial realization
• Independent programming of center frequency and quality factor
• Supports multiple filter modes including bandpass, lowpass, and highpass

Applications

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

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for obsolescence notices from Analog Devices. Ensure supply chain stability as availability may be restricted or limited due to product lifecycle status.

Selection Notes

Select this model when extended center frequency ranges up to 140kHz are required compared to the MAX260 or MAX261 variants. Verify that the commercial temperature range meets system requirements. Ensure the design accommodates the specific clock-to-f0 ratio limitations inherent to the MAX262 architecture.

Part Context

This component belongs to the MAX260/MAX261/MAX262 family of CMOS dual second-order universal switched-capacitor active filters. The MAX262 variant specifically targets higher operating frequencies by employing lower sampling ratios relative to the other family members.
