< Back CMR Ratio in Dual JFETs Introduction When choosing the optimal JFET for a new circuit, a characteristic often overlooked is how the part’s design affects the rejection of unwanted inputs while amplifying the signal as accurately as possible. Single JFETs provide excellent impedance matching and low-noise amplification, but lack one important quality of their dual counterparts – dual discrete devices largely reject common signals. This important characteristic – Common Mode Rejection – means that selecting the right dual JFET can be the most cost-effective way of improving signal-to-noise ratio in a design. Read More

P-CHANNEL JFET, VOLTAGE CONTROLLED RESISTOR < Back LS26VPS_ P-CHANNEL JFET, VOLTAGE CONTROLLED RESISTOR The LS26VPS is a P-Channel Single JFET voltage-controlled resistor. It has a drain-source resistance that is controlled by a DC bias voltage (VGS) applied to a high impedance gate terminal. Minimum RDS of 20 Ω occurs when VGS = 3.0V. As VGS approaches the pinch-off voltage of 7.5V, RDS rapidly increases to the maximum value or RDS = 50 Ω. For the N-Channel version, please see our LS26VNS. Both the N and P-channel parts are made from the same die geometry, making them complimentary.
