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.
