MAX297EPA

Overview

The MAX297EPA is a dual low bias current precision operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a ceramic DIP-8 package and operates within a supply voltage range of 4V to 40V. The device exhibits a typical input bias current of 20pA, an input offset voltage of 25µV, and a gain-bandwidth product of 500kHz. It supports a wide operating temperature range from -40°C to +85°C and utilizes a standard through-hole installation type.

Feature Summary

• Dual channel precision operational amplifier architecture
• Ultra-low input bias current characteristics
• Wide single or dual supply voltage operation capability

Applications

• High impedance sensor signal conditioning
• Precision instrumentation circuits
• Low leakage integrator applications

Procurement Notes

Verify the specific manufacturer designation as Analog Devices Inc. or Maxim Integrated for this part number. Confirm the package type matches the required DIP-8 form factor. Check RoHS compliance status against project requirements. Ensure the operating temperature range meets environmental specifications. Validate pinout compatibility with existing board layouts.

Selection Notes

Select this component when ultra-low input bias current is critical for maintaining accuracy in high-impedance circuits. Compare the 500kHz gain-bandwidth product against system bandwidth requirements. Evaluate the 25µV input offset voltage specification for precision needs. Consider the ceramic DIP-8 package for through-hole assembly processes.

Part Context

The MAX297 belongs to the OP297 family of dual precision operational amplifiers known for their Difet input stage technology. This series provides exceptional DC precision combined with low power consumption. The MAX297 variant specifically denotes the industrial temperature grade version packaged in a ceramic dual in-line format suitable for robust electronic assemblies.

Replacement Considerations

The OP297EPA serves as a direct functional equivalent from Analog Devices. Verify pinout compatibility before substitution. Ensure the replacement meets the same 20pA bias current and 500kHz bandwidth specifications.
