LM108AJ-8/B

Overview

The LM108AJ-8/B is a standard general-purpose operational amplifier manufactured by Rochester Electronics, LLC. It features a single circuit configuration housed in a 14-pin CERDIP package. The device supports a maximum supply voltage span of 40 V and operates within an extended temperature range of -55°C to +125°C. Key electrical specifications include a common-mode rejection ratio (CMRR) of 70 dB and an input offset voltage (Vos) of 500 µV. This component is classified as a super gain op amp designed for robust performance in demanding environments.

Feature Summary

• Super gain operational amplifier architecture
• Extended industrial temperature rating capability
• High common-mode rejection performance

Applications

• Industrial control systems requiring wide temperature tolerance
• Precision instrumentation circuits
• Signal conditioning in harsh environments

Procurement Notes

Verify the specific manufacturer lot date code and traceability documentation upon receipt. Ensure the physical package matches the 14-pin CERDIP specification. Confirm RoHS compliance status if required by your assembly process. Cross-reference the part number with official Rochester Electronics datasheets to validate pinout and electrical characteristics before integration into final designs.

Selection Notes

Select this component when a high-gain operational amplifier is required for applications involving significant temperature variations. The 14-pin ceramic dual in-line package offers superior thermal stability compared to plastic alternatives. Consider the 500 µV input offset voltage for precision requirements. Evaluate the 70 dB CMRR against noise immunity needs in your specific circuit topology.

Part Context

Rochester Electronics specializes in providing lifecycle support for obsolete and end-of-life semiconductor components. The LM108 series represents a legacy monolithic operational amplifier originally developed for military and aerospace applications. This specific variant maintains the original performance characteristics while being produced under current manufacturing standards. It serves as a critical replacement for older systems requiring continued availability of proven analog technology.

Replacement Considerations

Direct replacements must match the 14-pin CERDIP package and LM108 electrical specifications. Verify compatibility with existing board layouts due to the specific pinout configuration. Alternative sources should provide equivalent temperature ratings and supply voltage limits.
