2N6908 SERIES N-Channel JFET Circuits The 2N690B Series is much more than a JFET. The addition of back-to-back diodes effectively clamps input "over-voltage" while a high-performance JFET provides an effective amplification stage. With the addition of a source resistor, a plete mon-source amplifier is created which provides both low leakage ,and very low noise. This performance is especially effective as a small signal pre-amplifier as well as impedance matching between low and high impedance sources. Finally, its TO-72 package is hermetically sealed and is available with full military screening per MIL-S-19500. (See Section 1.) For additional design information please see...
