Description for the XTR115
The XTR115 and XTR116 (XTR11x) are precision current output converters designed to transmit analog 4mA to 20mA signals over an industry standard current loop. These devices provide accurate current scaling and output current limit functions.
The on-chip voltage regulator (5V) can be used to power external circuitry. A precision on-chip VREF (2.5V for the XTR115 and 4.096V for the XTR116) can be used for offsetting or to excite transducers. A current return pin (IRET) 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 4mA to 20mA current transmission.
The XTR11x are specified for operation over the extended industrial temperature range, –40°C to +85°C.
