Overview
The LS5912 is a monolithic dual N-channel JFET amplifier in an SOT-23-6L package. It offers low noise with equivalent input voltage of 4 nV/√Hz at 10kHz and high transconductance (gfs) ranging from 4000 to 10000 µS at 1kHz. The device supports a gate-to-source breakdown voltage of -25V, continuous power dissipation of 500mW, and operates within a temperature range of -55°C to +150°C.
Feature Summary
- Dual N-channel JFET architecture for balanced signal processing
- Low noise performance suitable for precision analog applications
- High transconductance enabling wideband amplification
- Compact surface-mount packaging for space-constrained designs
Applications
- Precision instrumentation amplifiers
- Low-noise preamplifier stages
- Wideband signal conditioning circuits
- Balanced differential input stages
Procurement Notes
Verify the specific suffix 'ROHS' against the manufacturer's current documentation to confirm material compliance status. Ensure the ordering code matches the exact pinout and electrical specifications listed in the official datasheet. Confirm that the SOT-23-6L package variant aligns with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select the LS5912 when low input noise and high transconductance are critical for wideband applications. Compare its -25V breakdown voltage and 500mW power dissipation against system requirements. Consider the SOT-23-6L package size for assembly constraints. Evaluate thermal derating needs if operating above 25°C ambient temperature.
Part Context
Linear Integrated Systems manufactures the LS5912 as part of a family including LS5911 and LS5912C. These devices serve as improved replacements for legacy discrete JFET pairs like the 2N5911 and 2N5912. The company specializes in precision semiconductor components derived from expertise at Intersil and Union Carbide.
Replacement Considerations
Publicly confirmed substitutes include the SILICONIX, FAIRCHILD, and NATIONAL 2N5911 and 2N5912 discrete JFET pairs. Verify pin compatibility and electrical parameter margins when transitioning from these legacy discrete components to the monolithic LS5912 solution.
