Linear Integrated Systems LSK389 Monolithic Dual N-Channel JFET Amplifiers

Linear Integrated Systems LSK389 Monolithic Dual N-Channel JFET Amplifiers feature tight-offset voltage and remarkable stability over temperature. The Linear Integrated Systems LSK389 JFETs are designed to deliver performance in various applications. With a broad range of offset and drift specifications, select the optimal combination to meet exact requirements. The LSK389 series is 100% noise tested, balancing low noise and input capacitance.

Features

  • Unique monolithic dual-design construction of interleaving JFETs on the same piece of silicon
  • Excellent matching and thermal tracking
  • Great for maximizing battery-operated applications by providing a wide output swing
  • en= 1.9nV/√Hz (typ.), f= 1kHz and NBW= 1Hz ultra-low-noise
  • Improved second source replacement for 2SK389
  • A high signal-to-noise ratio as a result of the LSK389's low and tightly matched gate threshold voltages
  • IVGS1-2I= 20mV max tight matching
  • BVGSS= 40V max high breakdown voltage
  • Gfs= 20mS (typ.) high gain
  • 25pF (typ.) low capacitance
