CA3130AE

Instrumentation, Op Amps, Buffer Amps Overview

The CA3130AE is a monolithic integrated circuit operational amplifier manufactured by Renesas Electronics Corporation. It features a BiMOS construction that combines the high input impedance of MOS technology with the low offset voltage and drift characteristics of bipolar junction transistors. The device incorporates an internal compensation capacitor, eliminating the need for external frequency compensation components. It is designed to operate within a wide supply voltage range, supporting both single and dual power supplies.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• High input impedance achieved through MOS gate structure
• Low input offset voltage and drift due to bipolar output stage
• Internal frequency compensation for stability without external components
• Wide common-mode and differential voltage ranges compatible with standard logic levels

Instrumentation, Op Amps, Buffer Amps Applications

• Sample-and-hold circuits requiring high input impedance
• Integrators and precision rectifiers
• Transducer amplifiers
• Track-and-hold applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific manufacturer marking and date code on the physical component to confirm authenticity as a Renesas product. Ensure the package type matches the required PCB footprint, typically SOIC-8 or DIP-8 for this series. Confirm that the operating temperature range meets the environmental requirements of the final assembly before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the CA3130AE when application design demands a combination of very high input impedance and fast slew rate. It serves as a direct replacement for older JFET-input op-amps in many legacy designs. Consider the package availability and thermal dissipation capabilities if operating near maximum supply voltage limits in enclosed environments.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the CA3130 family of BiMOS operational amplifiers. The 'AE' suffix typically denotes an extended industrial temperature range variant compared to commercial grade parts. This family is characterized by its ability to interface directly with TTL and CMOS logic circuits while maintaining analog performance metrics suitable for precision signal processing tasks.
