WEBENCH® Tools/XTR116: XTR116
TI Thinks Resolved
Part Number:
XTR116
Tool/software: WEBENCH® Design Tools I am using
XTR116
U/2K5 device for getting 4 - 20mA output current. I have seen the reference design TIPD190. I would like to know - Which resistor we can add as a Trim Pot to control the...

RE: [FAQ] The minimum output current of my 2-wire 4-20mA transmitter is greater than 4mA.
The current consumption of a 2-wire transmitter, sensor, and its driving circuitry needs to be below 4mA. As seen in the current flow diagram below for the
XTR116
, the output current, I O , is a summation of I IN , I RET , and I BJT . I IN and I BJT are...

XTR116: Selection criteria for and when to use the output capacitor
Part Number:
XTR116
Are there any app notes on the
XTR116
that discuss the selection purpose, selection criteria and guidelines for the output capacitor. The datasheet doesn’t mention how to select this component, what effect the value has on the...

RE: XTR116: XTR116 measuring problem
Hi Yasin, As Kai has mentioned, the minimum output current of the
XTR116
is the quiescent current consumption of the
XTR116
and the consumption of the complete two-wire driver circuit. Please review the blog below. 2-Wire 4-20mA Sensor Transmitters...

RE: XTR106: Iret pins tied together if Loop - pins are isolated?
Hi Katlynne, I tried writing some equations, but when I went back and read your analysis again, it really helped that it was just first-principles of opamps! I agree, the negative feedback will try to drive the voltage difference between the inverting...
