D The XTR117 is a precision current output converter designed
to transmit analog 4-20mA signals over an industry-standard
current loop. It provides accurate current scaling and output
current limit functions. LOW QUIESCENT CURRENT: 130ОјA
5V REGULATOR FOR EXTERNAL CIRCUITS
LOW SPAN ERROR: 0.05%
LOW NONLINEARITY ERROR: 0.003%
WIDE-LOOP SUPPLY RANGE: 7.5V to 40V
MSOP-8 AND DFN-8 PACKAGES The on-chip voltage regulator (5V) can be used to power
external circuitry. A current return pin (IRET) senses any
current used in external circuitry to assure an accurate
control of the output current. APPLICATIONS The XTR117 is a fundamental building block of smart
sensors using 4-20mA current transmission. The XTR117 is
specified for operation over the extended industrial
temperature range, -40В°C to +125В°C. D TWO-WIRE, 4-20mA CURRENT LOOP
