MAX7415EUA+

Overview

The MAX7415EUA+ is a fifth-order, lowpass, elliptic switched-capacitor filter operating from a single +3V supply. It features a clock-to-corner frequency ratio of 100:1, allowing corner frequencies from 1Hz to 15kHz with a transition ratio of 1.25 and typical stopband rejection of 37dB. The device draws 1.2mA in operating mode and reduces to 0.2µA in shutdown mode. It offers -80dB THD plus noise, ±4mV output offset, and supports self-clocking via an external capacitor or external clock input for precise control.

Feature Summary

• Fifth-order elliptic lowpass response with sharp rolloff
• Clock-tunable corner frequency range from 1Hz to 15kHz
• Low-power operation with dedicated shutdown mode
• Single-supply +3V operation capability

Applications

• ADC anti-aliasing
• Post-DAC filtering
• Speech processing

Procurement Notes

Verify the component matches the specific +3V supply requirement and 8-pin µMAX package configuration. Confirm that the ordering suffix corresponds to the extended temperature range (-40°C to +85°C) as indicated by the 'E' designation in the part number structure.

Selection Notes

Select this component when a steep rolloff with a transition ratio of 1.25 is required alongside low power consumption. Ensure the system operates on a single +3V supply and requires a maximum corner frequency of 15kHz. Consider the internal oscillator or external clock options based on the desired cutoff frequency stability requirements.

Part Context

This device belongs to the MAX7408/MAX7411/MAX7412/MAX7415 family of elliptic filters. While sharing similar architectures, the MAX7415 is specifically optimized for +3V single-supply applications, distinguishing it from the +5V variants within the same series.
