Part Number: XTR300 Other Parts Discussed in Thread: XTR305 , TIPD155 As per the Reference design of XTR300
TIPD155
It is a Two-Channel Source/Sink Combined Voltage & Current Output. But in this document no where shows the design for Sinking Current output…
HI Shiblin,
- The XTR111 is a current output transmitter. On the multiplexer circuit above, when selecting the RLOAD = 249Ω, the resulting output voltage will change with any additional load impedance or resistance applied at the output of MUX U38…
Hi,
Thank you for your detail explanation..
Can i use XTR300 for Source and Sink Outputs. Can you please share the reference document for Source and Sink output,
I referred the TIPD155 document for 2-channel Source/Sink Combined mode V/I output.
Here…
HI Shibin,
As Kai has mentioned, on the current transmitter application, the main issue with the Howland Current source configuration is that could be sensitive to capacitive/inductive load and will likely become unstable while driving a long cable. There…
HI Joe,
Below are a few XTR300 and XTR305 reference designs that could be of interest.
XTR300: TIDA-00454 , TIPD155
XTR305: TIDA-01633
Thank you and Regards,
Luis
Hello,
Attached are a couple of reference designs using the XTR300 that show the expected measured performance. The designs shows detailed hardware measurements and a few plots with the expected performance on a similar configuration to your requirement…
Hi,
Please have a look at the TIPD155 Which is dual channel version, and you can extend the same to 16 channel with DAC81416.

Hello Mike,
Thanks for the detailed explanation. The DAC8750 can be used with a minimum of 10V for the analog supply and unfortunately that wouldn't help solve the problem. Please check out TIPD155. It uses a partially discrete approach to generate two…
If you are attempting to use 2-wire transmitters, you will need to isolate the input to each transmitter. The I RET pin of a 2-wire transmitter needs to float and cannot be tied to other grounds or the I RET of other transmitters. See the attached articles…
