Overview
The LF411CP is a precision operational amplifier manufactured by Texas Instruments, featuring a JFET input stage. It provides a gain-bandwidth product of 8 MHz and a slew rate of 25 V/µs. The device operates within a supply voltage range of ±3.5 V to ±18 V (7 V to 36 V total). Key electrical specifications include an input offset voltage of 500 µV, input bias current of 60 pA, and common-mode rejection ratio of 100 dB. It consumes 2.5 mA of operating current and exhibits an input voltage noise density of 18 nV/√Hz. The component is housed in an 8-pin PDIP package for through-hole mounting.
Feature Summary
- JFET input stage design ensures low input bias current and high input impedance.
- Precision characteristics with low input offset voltage and drift suitable for accurate signal conditioning.
- High slew rate and gain-bandwidth product support fast transient response and wide bandwidth applications.
Applications
- Precision instrumentation circuits
- Audio processing stages
- Data acquisition systems
Procurement Notes
Verify the manufacturer part number LF411CP against official Texas Instruments documentation to confirm authenticity. Ensure the ordering suffix matches the required package type and temperature rating. Cross-reference datasheet revisions to validate electrical parameters before integration into designs.
Selection Notes
Select this component when JFET inputs are required for minimal loading on high-impedance sources. Compare performance metrics such as input bias current and offset voltage against alternative op-amps. Confirm that the PDIP package and through-hole mounting style align with the PCB layout requirements.
Part Context
The LF411 belongs to the LF411 family of single-channel precision operational amplifiers. It is part of Texas Instruments' broader portfolio of analog signal chain components designed for general-purpose and specialized analog applications requiring high performance and stability.
Replacement Considerations
Consult official substitution guides for pin-compatible alternatives. Verify that any replacement maintains equivalent JFET input characteristics and electrical specifications.
