CA3080M-G

Overview

The CA3080M-G is a high-performance operational amplifier manufactured by Rochester Electronics, LLC. It features a transconductance architecture housed in an 8-pin plastic DIP package. The device exhibits a maximum input offset voltage of 5000 µV and a bandwidth of 2 MHz. Key electrical characteristics include a typical common-mode rejection ratio of 110 dB and a maximum average bias current of 15 µA. Internal frequency compensation ensures stability across various configurations.

Feature Summary

• Transconductance operational amplifier architecture
• Internal frequency compensation for stability
• High common-mode rejection ratio
• Plastic dual in-line packaging

Applications

• Precision analog signal processing circuits
• Instrumentation amplifier front-ends
• Active filter designs requiring high CMRR
• Voltage-to-current conversion stages

Procurement Notes

Verify the manufacturer designation as Rochester Electronics, LLC, which often handles surplus or discontinued inventory from original manufacturers like Harris or Intersil. Confirm the specific suffix 'G' against official datasheets to ensure compliance with environmental standards and pinout compatibility before integration into production designs.

Selection Notes

Select this component when a robust bipolar transconductance amplifier is required with moderate bandwidth and high common-mode rejection. Consider the 5000 µV offset voltage limit for applications where precision trimming is not feasible. Ensure the PDIP8 package fits the available board space and thermal requirements of the target system.

Part Context

This part belongs to the CA3080 family of operational amplifiers, originally developed by Harris Semiconductor and later acquired by Intersil and Renesas. Rochester Electronics provides these components as a source for legacy systems requiring continued availability of established analog building blocks.

Replacement Considerations

Direct replacements include the CA3080AE and CA3080E variants from Harris or Intersil. Verify pin compatibility and electrical parameter tolerances against the specific application requirements before substituting.
