MAX7407ESA-T

Overview

The MAX7407ESA-T is an eighth-order lowpass elliptic active filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes switched-capacitor technology to achieve a cutoff frequency of 10 kHz. The device operates on a single 5 V supply, with a valid operating range between 4.5 V and 5.5 V. Designed for surface-mount applications, it is housed in an 8-pin SOIC package. The component supports an industrial temperature range from -40°C to +85°C. It functions as a single-channel signal processing unit suitable for precision analog filtering tasks.

Feature Summary

• Implements high-selectivity elliptic response using switched-capacitor architecture
• Provides precise frequency control via external clock input
• Operates efficiently within standard single-supply voltage ranges

Applications

• Anti-aliasing filtering in data acquisition systems
• Signal conditioning for sensor interfaces
• Audio processing circuits requiring steep roll-off characteristics

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm that the ordered part matches the exact electrical specifications required for the target application environment.

Selection Notes

Select this component when an eighth-order elliptic response is necessary for sharp attenuation. Verify that the system clock frequency allows for proper operation at the desired 10 kHz cutoff. Ensure the design accommodates the switched-capacitor nature of the filter regarding input impedance and clock feedthrough effects.

Part Context

This part belongs to the MAX7407 family of switched-capacitor filters. It shares functional similarities with other members like the MAX7400 but differs in order and response type. The ESA variant specifically denotes the surface-mount SOIC package option, distinguishing it from through-hole DIP versions within the same product line.
