Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied.

The XTR117 is a precision current output converter designed to transmit analog 4-20mA signals over an industry- standard current loop. It provides accurate current scaling and output current limit functions.

The on-chip voltage regulator (5V) can be used to power external circuitry. A current return pin (IRET) senses any current used in external circuitry to assure an accurate control of the output current. The XTR117 is a fundamental building block of smart sensors using 4-20mA current transmission. The XTR117 is specified for operation over the extended industrial temperature range, −40°C to +125°C.
