Bare Die Product Detail: LSK389A

N-Channel Dual Monolithic:
Monolithic Dual N-Channel JFET amplifier - Ultra-low noise, low drift, low capacitance. The LSK389A uses a unique interleaved construction to deliver excellent matching & thermal tracking with high signal-to-noise ratio.

LSK389A is an improved replacement for discontinued Toshiba 2SK389 & cross-reference replacement for Interfet, Intersil, Motorola, National / Fairchild, Philips, Vishay / Siliconix 2N5196, 2N5197, 2N5198, 2N5199. For single version see LSK170.

Features:

Wide output swing & high signal-to-noise ratio
Narrow I_DSS range for ease of tolerance in low voltage applications
40V breakdown for max linear headroom in high transient program content amplifiers
Low input noise to capacitance product with nearly zero popcorn noise

Applications:

Audio amplifiers & pre-amplifiers
Discrete low-noise operational amplifiers
Battery operated audio pre-amplifiers
Guitar pickups, effects pedals, microcphones, audio mixer consoles
Acoustic sensors & Sonic imaging
Sonobuoys, hydrophones
Chemical & radiation detectors
Instrumentation amplifiers
Accelerometers
CT scanner input stage
Oscilloscope input stage
Electrometers
Vibration detectors
