MAX7410CUA+T

Overview

The MAX7410CUA+T is a fifth-order, lowpass switched-capacitor filter (SCF) from the Analog Devices/Maxim Integrated MAX7409/MAX7410 family. It provides a Butterworth response with a maximally flat passband and operates on a single +5V supply. The device draws 1.2mA in operating mode and reduces to 0.2µA in shutdown mode. Corner frequencies are tunable from 1Hz to 15kHz using a fixed 100:1 clock-to-corner ratio via internal or external clocking. It features an offset adjust pin for DC level control and is housed in an 8-pin µMAX package.

Feature Summary

• Butterworth filter response providing a maximally flat passband
• Clock-tunable corner frequency ranging from 1Hz to 15kHz
• Low-power operation with dedicated shutdown mode
• Single-supply +5V operation capability

Applications

• ADC anti-aliasing
• DAC postfiltering
• Speech processing
• CT2 base stations
• Air-bag electronics

Procurement Notes

Verify the specific ordering suffix '+T' against official manufacturer documentation to confirm tape-and-reel packaging status. Ensure the component matches the standard MAX7410CUA specifications regarding temperature range and package type before procurement.

Selection Notes

Select this part when a maximally flat Butterworth response is required rather than the Bessel response found in the MAX7409. Confirm that the application requires a +5V single supply, as the MAX7413/14 variants operate at +3V. Verify that the 100:1 clock-to-corner frequency ratio aligns with system timing constraints.

Part Context

The MAX7410 belongs to a family of fifth-order lowpass switched-capacitor filters manufactured by Maxim Integrated, now part of Analog Devices Inc. This series includes the MAX7409, MAX7410, MAX7413, and MAX7414, differentiated primarily by their filter response characteristics and operating voltage requirements.

Replacement Considerations

The MAX7414 serves as a functional substitute if the application can accommodate a +3V supply instead of +5V. The MAX7409 offers a similar form factor but provides a Bessel response rather than the Butterworth characteristic of the MAX7410.
