LS5911 SOT-23 6L ROHS

Overview

The LS5911 is a monolithic dual N-channel JFET amplifier in a SOT-23 package. It features low noise with an equivalent input voltage of approximately 4nV/√Hz at 10kHz and high transconductance (gfs) ranging from 4000µS to 10000µS at 1kHz. The device supports a maximum power dissipation of 500mW, operates within a junction temperature range of -55°C to +150°C, and provides a gate-to-source breakdown voltage of -25V.

Feature Summary

Monolithic dual N-channel JFET architecture
Low noise performance suitable for precision applications
High transconductance for wideband signal processing
Improved replacement for legacy discrete JFETs

Applications

Precision instrumentation amplifiers
Low-noise preamplifier stages
Wideband signal processing circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to ensure correct pinout and electrical tolerances. Confirm RoHS compliance status as indicated on the datasheet. Cross-reference the component marking with official Linear Integrated Systems identification guides to prevent counterfeit parts. Ensure storage conditions adhere to the specified temperature limits.

Selection Notes

Select this component when a matched dual JFET pair is required for differential or balanced circuit topologies. Consider the low noise figure and high transconductance for sensitive analog front ends. Evaluate the thermal derating requirements if operating above 25°C ambient temperature. Compare specifications against legacy replacements like the 2N5911 to verify performance improvements.

Part Context

Linear Integrated Systems manufactures the LS5911 as part of their precision semiconductor portfolio. The company leverages expertise from historical entities such as Intersil and Union Carbide. This component serves as a modernized alternative to older discrete JFET technologies, offering integrated matching characteristics within a compact surface-mount footprint.
