describe
LTS110 is a V/I converter that can linearly convert analog voltage into 0-20mA/4-20mA; Users can set the desired output range through an external Rset; External power transfer can be achieved through a transistor; LDO is the internal reference output, with a default output of 2.5V; Simplify V/I conversion design.
characteristic
