Linear Integrated Systems LSK489 Dual N-Channel JFETs

Linear Integrated Systems LSK489 Dual N-Channel JFETs feature low-input capacitance and low-noise technology. The Linear Integrated Systems LSK489 is ideal for precision instrumentation and sensor applications. The tight offset voltage and low drift over temperature range make it perfect for designers who need a high level of performance in components.

Features

  • en= 1.8nV/√Hz (typ.), f= 1kHz, NBW= 1Hz
  • Very low common source input capacitance of CISS= 4pF (typ.)
  • High slew rate
  • Low offset/drift voltage
  • Low gate leakage IGSS and IG
  • High CMRR 102dB
  • Tight differential voltage match vs. current
  • Improved Op-Amp speed settling time accuracy
  • Minimum input error trimming error voltage
  • Lower intermodulation distortion due to the low input capacitance

Applications

  • Wideband differential amplifiers
  • High-speed temperature compensated single-ended input amplifier
  • High-speed comparators
  • Impedance converters
  • Sonobouys and hydrophones
  • Acoustic sensors
