XTR115UA General Description

The XTR115 and XTR116 (XTR11x) are precision current output converters designed to transmit analog 4-mA-to-20-mA signals over an industry standard current loop. These devices provide accurate current scaling and output current limit functions.

The on-chip voltage regulator (5 V) can be used to power external circuitry. A precision on-chip V REF (2.5 V for the XTR115 and 4.096 V for the XTR116) can be used for offsetting or to excite transducers. A current return pin (I RET) senses any current used in external circuitry to provide an accurate control of the output current.

The XTR11x are a fundamental building block of smart sensors using 4-mA-to-20-mA current transmission.

The XTR11x are specified for operation over the extended industrial temperature range, –40°C to +85°C.
