MAX280EPA Equivalent & Substitute Parts

Part Overview

The MAX280EPA is a Butterworth, low pass switched capacitor filter IC manufactured by Analog Devices Inc./Maxim Integrated. It functions as a 5th order low pass filter with a 20kHz cutoff frequency, designed for signal conditioning and anti-aliasing applications in data acquisition systems. The device operates with dual supply voltages (4.75V ~ 16V or ±2.375V ~ 8V) and is housed in an 8-DIP through-hole package.

The MAX280EPA is classified as obsolete. Locating equivalent or substitute components is necessary for new designs, system upgrades, or when existing inventory becomes unavailable. Active alternatives with identical electrical and mechanical specifications are available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX280EPA is determined by strict equivalence across the following critical parameters:

• Filter topology and order (Butterworth, 5th order low pass)
• Cutoff frequency (20kHz)
• Supply voltage range (4.75V ~ 16V or ±2.375V ~ 8V)
• Package type and pin configuration (8-DIP through-hole)
• Moisture sensitivity classification (MSL 1)

The MAX280EPA+ qualifies as a direct substitute because it maintains identical electrical performance specifications and mechanical compatibility. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX280EPA+ is the appropriate selection for new designs and system replacements. It provides identical electrical and mechanical performance to the MAX280EPA while offering the following advantages:

• Active product status ensures long-term availability and manufacturer support
• ROHS3 compliance satisfies environmental and regulatory requirements for modern applications
• Equivalent supply voltage range and filter specifications enable direct pin-for-pin substitution
• Through-hole 8-DIP package maintains compatibility with existing PCB layouts

The MAX280EPA remains suitable only for legacy system maintenance where existing inventory is available and RoHS compliance is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can the MAX280EPA+ be used as a direct replacement for the MAX280EPA?

A: Yes. The MAX280EPA+ is electrically and mechanically equivalent. Both devices feature identical filter specifications (5th order Butterworth, 20kHz cutoff), supply voltage ranges (4.75V ~ 16V or ±2.375V ~ 8V), and 8-DIP package configuration. Pin-for-pin substitution is supported without circuit modification.

Q: What is the primary difference between these two parts?

A: The MAX280EPA+ is an active product with ROHS3 compliance, while the MAX280EPA is obsolete and RoHS non-compliant. Both maintain identical electrical performance and package specifications.

Q: Are there any packaging differences between MAX280EPA and MAX280EPA+?

A: Both devices use the same 8-DIP (0.300", 7.62mm) through-hole package. The MAX280EPA+ is supplied in tube packaging, while the MAX280EPA was supplied in standard packaging. This does not affect electrical or mechanical compatibility.

Q: Does the MAX280EPA+ require any circuit design changes?

A: No. The MAX280EPA+ maintains identical electrical specifications, including supply voltage range, filter order, cutoff frequency, and pin configuration. Existing circuit designs require no modification.

Q: What is the moisture sensitivity rating for these devices?

A: Both the MAX280EPA and MAX280EPA+ have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
