LS830 TO-71 6L ROHS

Overview

The LS830 TO-71 6L ROHS is a monolithic dual N-channel JFET amplifier manufactured by Linear Integrated Systems. It features ultra-low leakage and low drift characteristics, making it suitable for precision analog applications. The device utilizes a TO-71 metal can package with six leads (6L) and complies with RoHS standards. Key electrical parameters include a maximum gate current of 0.25 pA and a minimum forward transadmittance of 120 µmho. The maximum gate-source cutoff voltage is specified at 2 V, ensuring reliable operation in low-power environments.

Feature Summary

• Ultra-low leakage performance for high-impedance signal integrity
• Low drift characteristics for stable amplification over time
• High input impedance minimizing circuit loading effects
• Monolithic construction ensuring consistent dual-JFET matching

Applications

• Precision instrumentation amplifiers
• Sample-and-hold circuits
• Photodiode preamplifiers
• Electrometer inputs

Procurement Notes

Verify the specific manufacturer designation, as Linear Integrated Systems assets have been acquired by other entities. Confirm the RoHS compliance status directly with the current supplier or datasheet revision. Ensure the TO-71 6L package variant matches the required footprint and pinout for the target design.

Selection Notes

Select this component when ultra-low input bias current is critical. Compare against similar JFETs like the LS421 or LS5905 if different leakage or gain specifications are required. Consider the TO-71 package constraints regarding thermal dissipation and mounting requirements compared to surface-mount alternatives.

Part Context

This part belongs to the family of low-leakage dual N-channel JFET amplifiers from Linear Integrated Systems. It shares functional similarities with the LS421 and LS5905 but may differ in specific leakage or gain thresholds. The TO-71 package is a legacy hermetic option often used in military or high-reliability aerospace applications requiring robust environmental sealing.

Replacement Considerations

Potential substitutes include the LS421 or LS5905 from the same manufacturer family. Verify pin compatibility and electrical parameter overlaps before substitution. Cross-reference with equivalent parts from other manufacturers only if datasheets confirm identical leakage and gain specifications.
