DESCRIPTION
The VCR2N/4N/7N JFET voltage controlled resistors have an                    Key to device performance is the predictable rDS change
ac drain-source resistance that is controlled by a dc bias                   versus VGS bias where:
voltage (VGS) applied to their high impedance gate terminal.
Minimum rDS occurs when VGS = 0 V. As VGS approaches the                                                   r DS(@ V GS + 0)
pinch-off voltage, rDS rapidly increases. This series of junction
