Twin N-channel JFET lowers noise in precision instrumentation and sensors


The LS844 monolithic twin N-channel JFET from Linear Methods gives low enter capacitance, considerably lowering intermodulation distortion. Focusing on precision instrumentation and sensor purposes, the LS844 provides a mixture of excessive transconductance, low noise of two.5 nV/√Hz typical at 1 kHz, and low enter capacitance of simply 3 pF typical and eight pF most.

Constructed by interleaving each JFETs on the identical piece of silicon, the LS844 is ready to present superb matching and thermal monitoring. Most voltage and present for every transistor is 60 V (gate voltage to empty or supply) and 50 mA (gate ahead present), respectively.

Packaging choices for the twin JFET embrace surface-mount plastic SOIC 8L, PDIP 8L, and SOT-23 6L. It’s also supplied in TO-71 6L and TO-78 6L through-hole metallic cans. The LS844 within the SOT-23 6L package deal prices $1.19 every in plenty of 1000 items.
