Linear Systems JFETs LSK489 TO-71 6L ROHS

The LSK489 is a monolithic dual N-channel JFET amplifier designed for low-noise precision instrumentation and sensor applications. It is available in a TO-71 6L metal package with a maximum operating junction temperature of +150°C and a continuous power dissipation of 300 mW per side. The device features a typcial input capacitance of 4 pF, a noise voltage of 1.8 nV/√Hz at 1 kHz, and a gate-to-source breakdown voltage of -60 V. It maintains a common-mode rejection ratio of 102 dB and tight differential gate-to-source voltage match of up to 20 mV. The LSK489 meets RoHS standards and is pin-compatible with the LSK389 in TO-71 and SOIC packages.
