The XTR110 is a precision voltage-to-current converter designed by Texas Instruments. It can accept inputs of 0 to 5V or 0 to 10V and can be connected to outputs of 4 to 20mA, 0 to 20mA, 5 to 25mA and many other commonly used ranges.
The XTR110 precision voltage‑to‑current converter is designed for analog signal transmission in industrial process control, pressure/temperature transmitters, and test equipment. It accepts 0‑5 V or 0‑10 V inputs and can be configured for output ranges such as 4‑20 mA, 0‑20 mA, and 5‑25 mA. The device features a 0.005 % maximum non‑linearity, a 10 V internal reference, and single‑supply operation from 13.5 V to 40 V.
The XTR110 is offered in 16‑pin ceramic DIP, plastic DIP, and SOL‑16 surface‑mount packages, with commercial and industrial temperature‑range grades. Detailed electrical specifications, ordering information, and typical performance curves are provided, along with guidance for external resistor and transistor selection to extend the output span.
| Input Voltage Range | 0 V to +5 V, 0 V to +10 V |
|---|---|
| Output Current Range | 4 mA‑20 mA, 0 mA‑20 mA, 5 mA‑25 mA |
| Supply Voltage Range | 13.5 V to 40 V |
| Maximum Nonlinearity | 0.005 % of span |
| Quiescent Current (excluding output) | 3 mA‑4.5 mA |
| Commercial Temperature Range | -40 °C to +85 °C |
The XTR110 operates from a single supply voltage between 13.5 V and 40 V.
The output current range is set by selecting different pin connections and, if needed, adding an external resistor (RSPAN) to adjust the span; standard ranges include 4‑20 mA, 0‑20 mA, and 5‑25 mA.
The XTR110 accepts input voltages up to +5 V or +10 V, depending on the selected configuration.
It is available in 16‑pin ceramic DIP, 16‑pin plastic DIP, and SOL‑16 surface‑mount packages.
