Part Number: NPD5565
Function: N Channel JFET NPD5565
Package : mini-DIP 8 pin type
Manufacturer: National ( Texas Instruments )
The 2N5565 / NPD5564 thru 2N5566 / NPD5566 series of N-Channel monolithic dual JFETs is designed for broadband low noise differential amplifier or applications requiring dual matched moderate ON resistance analog switches.
Differential connection of National NPD5565 dual JFET is used when balanced inputs and low distortion are main requirements for AC amplifier, Combination with LF356 opamp shown gives gain of about 500. Noise is somewhat higher than with single-ended JFET.-“FET Databook,” National Semiconductor, Santa Clara, CA, 1977, p 6-17-6-19.
