MAX7410EUA+

Overview

The MAX7410EUA+ is a fifth-order, lowpass switched-capacitor filter with a Butterworth response. It operates from a single +5V supply and draws 1.2mA in normal mode, reducing to 0.2µA in shutdown. The corner frequency is tunable from 0.001kHz to 15kHz via an internal oscillator or external clock, maintaining a fixed 100:1 ratio. Key electrical parameters include a typical output offset voltage of ±4mV, a power-supply rejection ratio of 70dB, and a maximum capacitive load drive of 50pF. The device is housed in an 8-pin µMAX package.

Feature Summary

• Butterworth filter response for maximally flat passband
• Clock-tunable corner frequency from 1Hz to 15kHz
• Low-power shutdown mode reduces current to 0.2µA
• Single +5V supply operation

Applications

• ADC anti-aliasing
• DAC postfiltering
• Speech processing
• Air-bag electronics

Procurement Notes

Verify the specific suffix 'EUA+' against the manufacturer's official documentation to confirm the extended temperature range (-40°C to +85°C) and lead-free status. Ensure the ordering information matches the exact component marking on the physical device to avoid confusion with similar variants in the MAX7409/MAX7413/MAX7414 family.

Selection Notes

Select this component when a maximally flat Butterworth response is required rather than the Bessel response found in the MAX7409/MAX7413. Confirm that the system requires a +5V single supply, as the MAX7413/MAX7414 variants are designed for +3V operation. Verify that the 100:1 clock-to-corner frequency ratio aligns with the available clock sources in the design.

Part Context

This part belongs to the MAX7409/MAX7410/MAX7413/MAX7414 family of fifth-order lowpass switched-capacitor filters. While sharing the same pinout and general architecture, the MAX7410 is distinguished by its Butterworth response and +5V operating voltage, contrasting with the Bessel response and +3V requirements of other family members.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the MAX7410EPA (plastic DIP package) and MAX7410CUA (commercial temperature grade). For applications requiring a Bessel response instead of Butterworth, the MAX7409 series serves as a functional alternative.
