CA3140AMZ96

Overview

The CA3140AMZ96 is a single-channel general-purpose operational amplifier manufactured by Renesas Electronics Corporation. It features a BiMOS architecture with FET inputs and a bipolar output stage, housed in an 8-SOIC surface-mount package. Key electrical specifications include a gain-bandwidth product of 4.5 MHz, a slew rate of 9 V/µs, and an input bias current of 10 pA. The device operates within a supply voltage range of 4 V to 36 V, supports an output current of 40 mA per channel, and functions reliably across a temperature range of -55°C to 125°C.

Feature Summary

• BiMOS technology combining high-speed FET inputs with robust bipolar output stages for enhanced performance.
• Low input bias current characteristic suitable for precision signal processing applications.
• Wide common-mode and differential input voltage ranges exceeding the supply rails.

Applications

• High-impedance buffer circuits
• Sample-and-hold amplifiers
• Integrators and differentiators

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for recent Product Change Notifications regarding label updates or manufacturing site changes. Ensure the specific suffix matches the required packaging format for integration into production workflows.

Selection Notes

Select this component when high input impedance and wide bandwidth are required in a compact surface-mount form factor. Consider the 8-SOIC package dimensions for PCB layout constraints. Evaluate the thermal performance within the specified operating temperature range to ensure reliability under varying environmental conditions.

Part Context

This part belongs to the CA3140 series of operational amplifiers produced by Renesas Electronics. The series is characterized by its BiMOS construction, offering a balance between the low noise of bipolar transistors and the high input impedance of field-effect transistors. The CA3140AMZ96 variant specifically denotes the surface-mount version compliant with modern assembly standards.

Replacement Considerations

Cross-reference with CA3140MZ96 for similar specifications in alternative packaging. Verify pinout compatibility and electrical parameter alignment before substituting with other general-purpose op-amps from the same family.
