LSK170 ULTRA LOW NOISE SINGLE N-CHANNEL JFET Linear Systems replaces discontinued Toshiba 2SK170 with LSK170 The 2SK170 / LSK170 is an Ultra Low Noise Single N-Channel JFET Optimized to provide low noise at both high and low frequency with a narrow range of IDSS and low capacitance. The 2SK170 / LSK170’s low noise to capacitance ratio and narrow range of low value IDSS provide solutions for low noise applications which cannot tolerate high values of capacitance or wide ranges of IDSS The narrow ranges of IDSS binning with the 2SK170 / LSK170 promote ease of design tolerancing, particularly in low voltage applications. The 2SK170 / LSK170 is ideal for portable battery operated applications, and features high BVDSS for maximum linear headroom in high transient program content amplifiers. The 2SK170 / LSK170 series has a uniquely linear VGS transfer function for a stability that is highly desirable, particularly for audio front-end preamplifiers. 2SK170 / LSK170 Applications: Audio amplifiers and preamps, discrete low-noise operational amplifiers, battery-operated audio preamps, guitar pickups, effects pedals, microphones, audio mixer consoles, acoustic sensors, sonobuoys, hydrophones, chemical and radiation detectors, instrumentation amplifiers, accelerometers, CT scanners input stages, oscilloscope input stages, electrometers and vibrations detectors.
