The LS5019 is a single P-Channel JFET switch

LS5019

P-CHANNEL JFET

Linear Systems replaces discontinued Siliconix 2N5019

This p-channel analog switch is designed to provide low

on-resistance and fast switching.

The SOT-23 package provides ease of manufacturing,

and a lower cost assembly option.

(See Packaging Information).

LS5019 Applications:

Analog Switches

Commutators

Choppers

LS5019 Benefits:

Low Insertion Loss

No offset or error voltage generated by closed

switch

Purely resistive
