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.
Surface mount SOT23 available (not offered by Toshiba 2SK170)
Improved pin for pin replacement for Toshiba 2SK170
Improved functional replacement for Interfet IF1320, IF1330,
IF1331, and IF4500
