MAX7411EPA

Overview

The MAX7411EPA is a fifth-order, lowpass switched-capacitor filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single +5V supply and features a Butterworth response characteristic. The device allows for clock-tunable corner frequencies ranging from 1Hz to 15kHz, making it suitable for applications requiring precise frequency selection without external components. It draws 1.2mA in operating mode and includes a shutdown mode that reduces current consumption to 0.2µA. The component is housed in an 8-pin DIP package.

Feature Summary

• Fifth-order lowpass filtering with Butterworth response
• Clock-tunable corner frequency adjustable from 1Hz to 15kHz
• Single +5V supply operation capability
• Low power consumption with dedicated shutdown mode

Applications

• ADC anti-aliasing
• DAC post-filtering
• Speech processing
• Air-bag electronics

Procurement Notes

Verify manufacturer attribution carefully, as the part originates from Maxim Integrated, now part of Analog Devices. Confirm the specific EPA package variant matches design requirements. Check for obsolescence status or lifecycle changes due to corporate integration. Ensure compatibility with existing +5V system architectures before procurement.

Selection Notes

Select this component when a fixed fifth-order Butterworth response is required for signal conditioning. It is appropriate for designs needing tunable cutoff frequencies via external clock signals rather than fixed RC networks. Consider the 8-pin DIP package for through-hole assembly needs. Evaluate power constraints against the 1.2mA active draw and 0.2µA shutdown state.

Part Context

This part belongs to the MAX7409/MAX7410/MAX7413/MAX7414 family of switched-capacitor filters. While similar devices share architectural traits, the MAX7411 specifically denotes the +5V supply version with Butterworth characteristics. It differs from the MAX7410 which may have different response types or pinouts depending on the specific datasheet revision. The EPA suffix indicates an 8-pin DIP package.

Replacement Considerations

Public confirmed substitutes include MAX7410EPA and MAX7413EUA within the same family. Verify response type (Butterworth vs Bessel) and supply voltage (+5V vs +3V) compatibility before substitution.
