MAX7412EUA+T

Overview

The MAX7412EUA+T is a single-channel, 5th-order elliptic lowpass switched-capacitor filter operating from a +3V supply. It features a clock-to-corner frequency ratio of 100:1, allowing corner frequencies from 1Hz to 15kHz. The device provides a transition ratio of 1.6 and typical stopband rejection of 53dB. Supply current is 1.2mA in operating mode and reduces to 0.2µA in shutdown mode. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin µMAX package.

Feature Summary

• Elliptic lowpass response with sharp rolloff
• Clock-tunable corner frequency capability
• Low-power shutdown mode availability
• Single-supply operation

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 intended temperature grade and tape-and-reel packaging format before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a steep transition ratio of 1.6 and high stopband rejection. Ensure the system can provide a stable clock signal or appropriate external capacitor for internal oscillator tuning to achieve the desired cutoff frequency.

Part Context

This part belongs to the MAX74xx family of 5th-order elliptic switched-capacitor filters. It shares architectural similarities with the MAX7408, MAX7411, and MAX7415 but is specifically optimized for +3V single-supply operation, distinguishing it from the +5V variants in the series.

Replacement Considerations

The MAX7415 serves as a functional alternative within the same family, offering identical electrical characteristics and pinout but designed for +3V operation with a sharper transition ratio of 1.25.
