DESCRIPTION

The XTR115 and XTR116 are precision current out­put converters designed to transmit analog 4-to-20mA
signals over an industry standard current loop. They
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 V
(2.5V for XTR115 and 4.096V for XTR116) can be

circuitry to assure an accurate control of the output
current.

The XTR115 is a fundamental building block of
smart sensors using 4-to-20mA current transmission.

The XTR115 and XTR116 are specified for opera­tion over the extended industrial temperature range,
–40°C to +85°C.

ELECTROSTATIC
DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
