Overview
The CA3140EZ is a single operational amplifier manufactured by Renesas Electronics Corporation. It utilizes BiMOS technology, integrating PMOS input transistors with bipolar output stages on a monolithic chip. Key electrical parameters include a bandwidth of 4.5MHz and a maximum offset voltage of 5000uV. The device operates within a temperature range of -40 to +85°C and is housed in an MBCY8 metal can package.
Feature Summary
- Combines high input impedance from gate-protected PMOS transistors with the high output current capability of bipolar transistors.
- Provides a wide common-mode input voltage range that typically extends to 0.5V below the negative supply rail.
Applications
- High-speed analog signal processing circuits
- Precision instrumentation requiring low bias current
- General-purpose amplification stages
Procurement Notes
Verify the manufacturer marking on the component body to confirm it originates from Renesas Electronics Corporation or an authorized licensee. Ensure the part number suffix matches the specific package and temperature grade requirements for your design. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.
Selection Notes
Select this component when a design requires the combination of MOSFET input characteristics and bipolar output drive strength. It serves as a direct replacement for industry-standard 1458 operational amplifiers in similar packages. Consider its 4.5MHz bandwidth and BiMOS architecture for applications demanding both speed and high input impedance.
Part Context
The CA3140 series represents a family of integrated circuit operational amplifiers. The CA3140EZ is the single-channel variant of this series. It shares core architectural features with dual-channel versions like the CA3240, maintaining compatibility with standard operational amplifier pinouts while offering distinct performance metrics defined by its BiMOS construction.
Replacement Considerations
The CA3140EZ is compatible with industry standard 1458 operational amplifiers in similar packages. Verify pinout compatibility before substituting other single-supply or dual-supply op-amps.
