Overview
The CA3140AMZ is a single-channel general-purpose operational amplifier manufactured by Renesas Electronics. It features a gain-bandwidth product of 4.5 MHz and a slew rate of 9 V/us. The device operates with input bias current of 40 pA and input offset voltage of 5 mV. Supply voltage ranges from 2 V to 18 V (dual) or 4 V to 36 V (single). It delivers 40 mA output current per channel with 70 dB CMRR and 80 dB PSRR. Input voltage noise density is 40 nV/sqrt Hz. Operating temperature spans -55 C to +125 C in an SOIC-8 package.
Feature Summary
- Utilizes BiFET technology for low input bias current
- Provides high slew rate performance for signal fidelity
- Supports wide supply voltage operation
- Features rail-to-rail output swing capability
Applications
- General-purpose analog signal conditioning
- Active filter circuits
- Buffer amplification stages
- Transducer interfaces
Procurement Notes
Verify the specific suffix 'Z' against the manufacturer's official datasheet to confirm RoHS compliance status and exact electrical tolerances. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Confirm that the operating temperature range meets your environmental specifications. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single-channel op amp with moderate bandwidth and low bias current is required. Compare the 4.5 MHz gain-bandwidth product against application needs. Evaluate the 9 V/us slew rate for dynamic signal handling. Consider the SOIC-8 package for surface-mount assembly constraints. Verify power supply compatibility within the specified voltage limits.
Part Context
The CA3140 series represents a family of BiFET operational amplifiers known for combining FET input characteristics with bipolar output drive capabilities. The CA3140AMZ is a specific variant within this lineage, offering enhanced performance metrics compared to earlier iterations. It serves as a direct replacement for legacy designs requiring low input current without sacrificing output drive strength.
Replacement Considerations
The CA3140AM is listed as a discontinued direct substitute. Verify pinout compatibility before substitution. Check if the older variant meets the same electrical specifications for your design.
