DESCRIPTION
The XTR110 is a precision voltage-to-current converter
designed for analog signal transmission. It accepts inputs
of 0 to 5V or 0 to 10V and can be connected for outputs of
4mA to 20mA, 0mA to 20mA, 5mA to 25mA, and many other
commonly used ranges.
A precision on-chip metal film resistor network provides input
scaling and current offsetting. An internal 10V voltage refer-
ence can be used to drive external circuitry.
The XTR110 is available in 16-pin plastic DIP, ceramic DIP
and SOL-16 surface-mount packages. Commercial and in-
dustrial temperature range models are available.
