LF411CDR

Overview

The LF411CDR is a precision JFET-input operational amplifier manufactured by Texas Instruments. It features a single channel in an 8-SOIC package. Key electrical parameters include a gain-bandwidth product of 8 MHz and a slew rate of 25 V/us. The input offset voltage is specified at 500 uV, with an input bias current of 60 pA. It operates on dual power supplies ranging from -15 V to +15 V, consuming 2.5 mA of supply current. Common-mode rejection ratio is 100 dB, and input voltage noise density is 18 nV/sqrt Hz. The device supports surface mount installation and functions within a temperature range of 0 C to +70 C.

Feature Summary

JFET input stage providing low input bias current
High common-mode rejection ratio for precision applications
Internal frequency compensation for stability

Applications

Precision signal conditioning circuits
High impedance sensor interfaces
Audio preamplifier stages

Procurement Notes

Verify the specific suffix 'CDR' corresponds to the tape and reel packaging format when ordering. Confirm that the commercial temperature grade (0 C to +70 C) meets the environmental requirements of the target application. Ensure compatibility with standard 8-SOIC footprint dimensions during PCB layout. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and current production status.

Selection Notes

Select this component for designs requiring low input bias current and high input impedance characteristics typical of JFET technology. Compare the 8 MHz bandwidth against system signal frequency requirements to ensure adequate gain-bandwidth performance. Evaluate the 25 V/us slew rate against maximum output signal transition speeds. Consider the 8-SOIC package constraints regarding thermal dissipation and board space availability relative to alternative packages.

Part Context

This device belongs to the LF411 series of precision operational amplifiers. It serves as a surface-mount variant of the legacy LF411 family, maintaining functional compatibility while adapting to modern assembly processes. The component integrates internal frequency compensation, eliminating the need for external capacitors in most standard configurations.
