MAX280CPA+ Equivalent & Substitute Parts

Part Overview

The MAX280CPA+ is a Butterworth, low pass switched capacitor filter IC manufactured by Analog Devices Inc./Maxim Integrated. This 5th order filter operates at a 20kHz cutoff frequency and is housed in an 8-PDIP through-hole package. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The MAX280CPA+ serves as a precision analog filtering solution for signal conditioning applications requiring low-pass filtering characteristics.

Substitute Part Grouping Explanation

Substitution for the MAX280CPA+ is determined by strict equivalence across the following critical parameters:

• Filter Type: Butterworth, Low Pass Switched Capacitor topology
• Filter Order: 5th order configuration
• Cutoff Frequency: 20kHz center frequency
• Number of Filters: Single filter per package
• Supply Voltage Range: 4.75V ~ 16V, ±2.375V ~ 8V dual supply capability
• Package Type: 8-DIP through-hole form factor
• Pin Configuration: 8-PDIP supplier device package

Only parts matching all these electrical and mechanical specifications qualify as direct substitutes. The MAX280CPA+ represents the current production equivalent for this filter specification.

Parameter Comparison

Engineering Selection Recommendations

The MAX280CPA+ is the direct equivalent part for this filter specification. Selection is based on the following engineering criteria:

• Active product status ensures ongoing manufacturing support and availability
• ROHS3 compliance satisfies environmental and regulatory requirements for commercial and industrial applications
• MSL 1 rating indicates no moisture sensitivity constraints during storage and handling
• 8-DIP through-hole package provides standard PCB integration for legacy and new designs
• Dual supply voltage capability (±2.375V ~ 8V) and single supply range (4.75V ~ 16V) accommodates diverse circuit topologies

No alternative parts with differing filter order, cutoff frequency, or package configuration are considered equivalent substitutes for this specification.

Frequently Asked Questions (FAQ)

Q: Can the MAX280CPA+ be replaced with a different filter order or cutoff frequency?

A: No. The 5th order Butterworth topology and 20kHz cutoff frequency are fundamental design parameters. Substitution requires exact matching of these specifications.

Q: Is the 8-DIP package interchangeable with surface-mount alternatives?

A: No. The MAX280CPA+ is specified as a through-hole 8-DIP package. Surface-mount variants, if available, would require PCB redesign and are not direct substitutes.

Q: What supply voltage configurations does the MAX280CPA+ support?

A: The device operates with single supply (4.75V ~ 16V) or dual supply (±2.375V ~ 8V). Circuit design must accommodate the selected supply configuration.

Q: Does the MAX280CPA+ require special handling or storage conditions?

A: MSL 1 rating indicates unlimited moisture sensitivity. Standard component storage practices apply without special environmental controls.

Q: Are there packaging options other than tube for the MAX280CPA+?

A: The provided specification lists tube packaging. Alternative packaging formats, if available from the manufacturer, would be distinct part numbers and require separate evaluation.
