HI Gonzalo,
The dominant portion of power dissipation for the current output is in the external FET. As Kai has explained, it is important to consider the power dissipated by the external FET, which is a function of the power supply voltage, and current…
Part Number: XTR111 Other Parts Discussed in Thread: OPA2197 , OPA2192 Hi all
My customer has started a project where they are evaluating the XTR111, they have these specs:
Input signal: 1V ... 4.5V, bandwidth 200kHz
Using the EVM they find that the bandwidth…
Hi Kirill,
As I understand things, this is a custom PCB design (not the XTR111-2EVM). Can you kindly post the complete schematic? If possible, please also post the layout gerber plots.
- Is the XTR111 exposed thermal pad connected to GND?
- Is the load…
Hi Krishna,
We want:
VIN: 0V to 10V
IOUT: 1uA to 1024uA
12V compliance
Looks like you have already done this with the XTR111: https://e2e.ti.com/support/amplifiers/f/14/t/837481?XTR111-2EVM-1uA-accuracy-with-modifications-in-the-circuit

Hi Sankar,
Yes, the XTR111 will perform to datasheet specs for supply voltages between 8V to 40V. We do not have a reference design for the XTR111, but we do have an evaluation module that can be found here: www.ti.com/.../xtr111-2evm.
This module is…
William,
For industrial applications you will almost always see things specified in terms of full-scale accuracy. It is typically a more useful measurement than relative accuracy. However, I have conducted my own temperature testing on our XTR111-2EVM…
Other Parts Discussed in Thread: XTR111-2EVM , INA138 , TPS62125 , XTR111 I came across a paper, written by Chris Glaser, regarding "Harnessing wasted engergy in a 4- to 20-mA current-loop systems"
I was wondering if you could give me a little help…
