Overview
The CA3080AE is a bipolar operational amplifier manufactured by Rochester Electronics, LLC. It features a transconductance architecture housed in an 8-pin PDIP package. Key electrical specifications include a maximum input offset voltage of 5000 µV and a bandwidth of 2 MHz. The device exhibits a typical common-mode rejection ratio of 110 dB with a minimum of 80 dB. Input bias current reaches 5 µA at 25°C and 15 µA maximum average. Internal frequency compensation is integrated for stability.
Feature Summary
- Transconductance operational amplifier architecture
- Integrated internal frequency compensation
- High common-mode rejection capability
- Bipolar process technology
Applications
- General-purpose analog signal processing circuits
- Instrumentation amplifier stages
- Active filter implementations
- Voltage buffer applications
Procurement Notes
Verify the specific datasheet revision and manufacturing lot details directly with Rochester Electronics to ensure compliance with required environmental standards and pinout configurations. Confirm that the PDIP-8 plastic package meets the mechanical constraints of the target assembly process before finalizing procurement decisions.
Selection Notes
Select this component when a robust bipolar op-amp with moderate speed and high CMRR is required. The 2 MHz bandwidth suits general audio or low-frequency control loops. Ensure the 5000 µV offset voltage aligns with system precision requirements compared to lower-offset alternatives.
Part Context
Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find discrete semiconductors and memory products. The CA3080AE represents a continuation of legacy designs originally developed by Harris Semiconductor and Intersil, providing availability for older industrial and military systems.
Replacement Considerations
Official substitute part numbers are not explicitly confirmed in the provided source material. Verify compatibility with generic equivalents such as the LM308 or original Harris variants only after confirming pinout and electrical parameter equivalence through official documentation.
