CA3130EZ

Overview

The CA3130EZ is a single-channel general-purpose operational amplifier manufactured by Renesas Electronics Corporation. It utilizes BiMOS technology, featuring MOSFET inputs and CMOS outputs to achieve high input impedance and low bias current. The device offers a gain-bandwidth product of 15 MHz and a slew rate of 30 V/µs. It operates within a supply voltage range of 5 V to 16 V and supports an operating temperature range from -55°C to 125°C. Packaged in an 8-pin PDIP format, it provides a maximum output current of 45 mA.

Feature Summary

• BiMOS architecture combining MOSFET input stage with CMOS output stage
• High input impedance with extremely low input bias current
• Single-ended output configuration for standard signal processing

Applications

• General-purpose analog signal amplification
• Buffer circuits requiring high input impedance
• Precision instrumentation front-ends

Procurement Notes

Verify the specific manufacturer designation on the component marking against the official Renesas or Intersil datasheet to confirm authenticity. Ensure the package type matches the required 8-pin DIP form factor. Check RoHS compliance status if environmental regulations apply to the final assembly. Confirm that the supply voltage requirements align with the system design constraints before integration.

Selection Notes

Select this component when high input impedance and low bias current are critical for the application circuit. The 15 MHz bandwidth suits moderate-speed signal processing tasks. Consider the 8-pin DIP package for through-hole mounting requirements. Evaluate the 5 V to 16 V supply range against available power rails. Compare performance metrics with other BiMOS op-amps if higher speed or lower noise is required.

Part Context

The CA3130 series belongs to a family of BiMOS operational amplifiers originally developed by Intersil and now produced by Renesas Electronics. These devices are designed to bridge the gap between JFET and bipolar op-amps, offering superior input characteristics while maintaining robust output drive capabilities. The CA3130EZ specifically denotes the commercial grade version in a plastic dual in-line package.
