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 VREF (2.5 V for the XTR115 and 4.096 V for A current return pin (IRET) senses any current used in external circuitry to provide an accurate control of the output current.
