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.
