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.

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.
