Description for the XTR117

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

The on-chip voltage regulator (5 V) can be used to power external circuitry. A current return pin (I RET) senses any current used in external circuitry to provide an accurate control of the output current.

The XTR117 is a fundamental building block of smart sensors using 4-mA-to-20-mA current transmission.

The XTR117 is specified for operation over the extended industrial temperature range, –40°C to +125°C.
