DESCRIPTION
The VCR2N/4N/7N JFET voltage controlled resistors have an
ac drain-source resistance that is controlled by a dc bias
voltage (V
GS
) applied to their high impedance gate terminal.
Minimum r
DS
occurs when V
GS
= 0 V. As V
GS
approaches the
pinch-off voltage, r
DS
rapidly increases. This series of junction
FETs is intended for applications where the drain-source
voltage is a low-level ac signal with no dc component.
Key to device performance is the predictable r
DS
change
versus V
GS
bias where:
