CA3130M

Overview

The CA3130M is a single-channel operational amplifier manufactured by Renesas Electronics, belonging to the CA3130 series. It utilizes a surface-mount SOIC-8 package with eight pins and measures 5mm in length and 1.5mm in height. The device operates within a supply voltage range of 6V to 16V and supports an operating temperature range from -55°C to 125°C. Key electrical specifications include a gain-bandwidth product of 50kHz, a slew rate of 30V/μs, an input bias current of 30pA, and an output current capability of 45mA.

Feature Summary

• Features BIMOS technology for high-speed performance combined with low input bias current characteristics.

Applications

• High-speed signal processing circuits requiring fast transient response.

Procurement Notes

Verify the specific manufacturer designation on the component marking, as this part was originally developed by Harris and Intersil before acquisition by Renesas. Confirm that the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the selected variant meets the required industrial temperature range specifications for your intended deployment environment.

Selection Notes

Select this component when a design requires a balance between moderate bandwidth and very low input bias current. The CA3130M is suitable for applications where input leakage must be minimized without sacrificing significant speed. Consider the 15mV maximum input offset voltage when designing precision analog stages.

Part Context

This component is part of the broader CA3130 family of operational amplifiers. The CA3130 series is historically known for combining the high input impedance of JFETs with the high slew rate of bipolar transistors through its unique BIMOS architecture. This specific model represents the standard commercial or industrial grade version in the SOIC-8 package.
