XTR117 4-20mA Current Loop Transmitter

The XTR117 is a

precision current output converter designed to transmit

analog 4mA to 20mA signals over an industry-standard current

loop. The device provides accurate current scaling and

output current limit functions.

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 provide an accurate control of the

output current.

The XTR117 is a

fundamental building block of smart sensors using 4mA to

20mA current transmission.

The XTR117 is

specified for operation over the extended industrial

temperature range, –40°C to +125°C.
