MAX280CPA+

Overview

The MAX280CPA+ is a dual, low-voltage operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.7V to 16V or dual supplies up to ±8V. The device features a high slew rate of 15V/µs and a bandwidth of 10MHz. It includes internal frequency compensation for stability in unity-gain configurations. The input common-mode voltage range extends to the negative rail, while the output swings within approximately 50mV of either supply rail. It is housed in an 8-pin PDIP package.

Feature Summary

• Dual operational amplifier architecture with integrated frequency compensation
• Single-supply operation capability extending to the negative rail
• High-speed performance characterized by 10MHz bandwidth and 15V/µs slew rate
• Rail-to-rail output swing capability close to both supply rails

Applications

• Active filtering circuits requiring high speed
• Video signal processing applications
• Portable instrumentation powered by single batteries
• Buffer amplifiers in data acquisition systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and packaging type (PDIP-8) against current datasheet specifications. Check for obsolescence notices or lifecycle changes prior to procurement planning.

Selection Notes

Select this component when dual op-amps are needed in single-supply environments. Ensure the load requirements stay within the specified output current limits. Consider thermal dissipation if operating near maximum voltage ratings. Verify that the required bandwidth exceeds 10MHz only if alternative devices are evaluated.

Part Context

This part belongs to the Maxim Integrated family of general-purpose operational amplifiers designed for cost-sensitive, high-volume applications. It serves as a standard solution for analog signal conditioning where moderate speed and low power consumption are balanced. The PDIP-8 package facilitates through-hole prototyping and assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other dual op-amps from the same manufacturer series for pin-compatible alternatives if necessary.
