MAX7415CPA

Overview

The MAX7415CPA is a fifth-order, lowpass, elliptic switched-capacitor filter integrated circuit manufactured by Analog Devices. It operates on a single supply voltage ranging from 2.7V to 3.6V and is housed in an 8-pin PDIP package. The device features a clock-tunable corner frequency adjustable between 1Hz and 15kHz. Key electrical specifications include a total harmonic distortion plus noise level of -80dB and a cutoff frequency centered at 15kHz. It is designed for applications requiring low noise and high precision signal filtering within compact surface-mount or through-hole configurations.

Feature Summary

• Provides fifth-order elliptic lowpass filtering characteristics for precise signal attenuation
• Features a clock-tunable corner frequency allowing flexible adjustment from 1Hz to 15kHz
• Delivers low noise and distortion performance with -80dB THD + Noise specification
• Supports single-supply operation for simplified power management in portable systems

Applications

• Audio signal processing and conditioning circuits
• Data acquisition system anti-aliasing filters
• Instrumentation front-end filtering stages
• Communication channel selection filters

Procurement Notes

Verify the specific ordering suffix to confirm package type and reel quantity. Ensure the supplier provides the official Analog Devices datasheet for the MAX7415 series. Confirm RoHS compliance status if required for your manufacturing process. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when a fixed 15kHz cutoff is appropriate for the application bandwidth. Consider the external clock source requirements for tuning the corner frequency. Evaluate the power supply constraints against the 2.7V to 3.6V operating range. Compare pin count and package size against available board space in the design.

Part Context

The MAX7415 belongs to the family of switched-capacitor filters from Analog Devices. These devices integrate complex analog filtering functions into small silicon areas. They replace traditional passive RC networks, offering better accuracy and stability without bulky components. This specific model focuses on audio-grade performance with elliptic response characteristics.

Replacement Considerations

The AD7412CPA is a documented similar device within the same product family. Verify pin compatibility and electrical specifications before substitution. Ensure the alternative part meets the same single-supply and clock-tuning requirements.
