DESCRIPTION
The XTR110 is a precision voltage-to-current con-
verter designed for analog signal transmission. It ac-
cepts inputs of 0 to 5V or 0 to 10V and can be
connected for outputs of 4 to 20mA, 0 to 20mA, 5 to
25mA and many other commonly used ranges.
A precision on-chip metal film resistor network pro-
vides input scaling and current offsetting. An internal
10V voltage reference can be used to drive external
circuitry.
The XTR110 is available in 16-pin plastic DIP, ce-
ramic DIP and SOL-16 surface-mount packages. Com-
mercial and industrial temperature range models are
available.
