LS3954A TO-71 6L ROHS

Overview

The LS3954A is a monolithic dual N-channel JFET amplifier featuring low drift and low noise characteristics. It provides a maximum temperature drift of 5µV/°C, typical gate leakage of 20pA, and typical voltage noise density of 10nV/√Hz. The device supports a maximum drain-source voltage of 60V and operates within a junction temperature range of -55°C to +150°C. Electrical performance includes a transconductance of up to 2000µS at full conduction and a common-mode rejection ratio exceeding 75dB.

Feature Summary

Monolithic dual N-channel JFET architecture
Low drift with maximum 5µV/°C temperature coefficient
Low leakage current with typical 20pA gate current
Low noise voltage density of 10nV/√Hz

Applications

Precision instrumentation amplifiers
High-impedance sensor interfaces
Low-noise preamplifier stages

Procurement Notes

Verify the specific suffix 'TO-71 6L ROHS' against official Linear Integrated Systems documentation to confirm package type and compliance status. Ensure the ordering code matches the exact datasheet revision for accurate electrical parameter alignment. Confirm availability through authorized distributors or direct manufacturer channels.

Selection Notes

Select the LS3954A when strict low drift and minimal gate leakage are required in dual JFET configurations. Compare against LS3954, LS3955, LS3956, and LS3958 variants based on specific drift and offset voltage tolerances. Consider the TO-71 package for hermetic sealing requirements or SOIC for surface mount applications.
