Frequently asked questions
How is the output current controlled on the XTR115?
The output current follows the input signal current on the IIN pin. Per the datasheet, an input current of 40 to 200 µA maps to the 4 to 20 mA output range.
What loop supply voltage does the XTR115 need?
The datasheet specifies a loop supply of 7.5 V to 36 V. The on-chip 5 V regulator can also power small external circuitry, subject to the datasheet limits.
