Linear Integrated Systems' the LSK389 series, which comprises an exceptional range of ultra-low-noise dual junction field effect transistors (JFETs). This series includes the LSK389A, LSK389B, LSK389C, and LSK389D models, each meticulously graded by IDSS. Notably, the LSK389B grade model has been specifically engineered to cater to the needs of ultra-high-end systems, spanning applications like U.S. Navy underwater listening, studio reference amplifiers, and microphones.
To guarantee adherence to datasheet specifications, every JFET in the LSK389 series undergoes rigorous individual noise testing. This ensures that customers can rely on the documented performance characteristics. Moreover, the dual JFETs are ingeniously interwoven using a proprietary design approach, resulting in optimal matching characteristics. This design innovation further enhances the overall performance and reliability of these JFETs, making them the preferred choice for demanding high-end audio and sensor applications.
