Linear Integrated Systems Launches the LSBF862

Linear Integrated Systems, based in Fremont, California, has recently unveiled the LSBF862, a state-of-the-art low noise N-channel JFET designed to fill the gap left by the discontinuation of the NXP BF862. When NXP ceased production of the BF862, many engineers faced significant challenges, including inadequate support for existing systems and the daunting task of requalifying new components to maintain product consistency. The LSBF862 arrives as a timely solution to these challenges, providing a high-performance alternative that delivers exceptional reliability and support.

Key Features and Benefits

The LSBF862 boasts an impressive low-noise performance with a specification of 4.0nV/√Hz at 10Hz, making it an ideal option for applications requiring high precision and minimal interference. Moreover, it features a higher minimum gate-source breakdown voltage of 40V, significantly surpassing that of its predecessor. This enhancement is complemented by high input impedance, which contributes to its versatility across various applications.

One of the standout aspects of the LSBF862 is its introduction of special testing options for essential DC parameters such as Vgs(off) and IDSS. This customization capability allows design engineers to optimize circuit performance beyond the standard datasheet limits, fostering innovation in design and implementation. The device is available in both SOT-23 packaged and bare-die versions, catering to diverse engineering needs.

Performance Under Pressure

Built on a radiation-tolerant JFET process, the LSBF862 ensures reliable performance even in the most demanding environments, eliminating the need for additional processing steps. This robustness extends its use in various critical fields including medical instrumentation, audio applications, sensor technologies, underwater acoustics, and test measurement systems.

Cindy Johnson, CEO of Linear Integrated Systems, stated, "The LSBF862 empowers design engineers and procurement teams with enhanced performance and long-term supply continuity, ensuring that legacy systems can be maintained efficiently." This commitment to reliability and performance places the LSBF862 as a premier choice among its peers in the semiconductor market.

Applications

The LSBF862 is perfectly suited for a wide array of applications such as:

• - Analog front-ends
• - Low noise amplifiers
• - Discrete low-noise operational amplifiers
• - Transimpedance amplifiers (TIA)
• - Photo diode amplifiers
• - Acoustic amplifiers
• - High impedance probes
• - Battery-operated amplifiers
• - Ultra-sensitive sensors
• - Microphones

The benefits of this JFET extend to reduced power consumption and longer battery life in low-power applications, making it an invaluable component for modern electronic devices.
