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 4 to 20mA, 0 to 20mA, 5 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 reference 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 industrial temperature range models are available.
