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…
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…
Hi David,
The primary reason for isolating in the digital domain is that it is relatively easy to isolate a digital signal and reproduce it accurately without any issues than an analog signal directly. Isolating an analog channel directly will pose many…
Hi Shinichi,
Thank you for your query. For question 1, if you could ask a more specific question I can check with the design team and get back. We will not be able to share the design level architecture. For question 2, you can refer to the following…
Hello,
Could you share the link to the page where you downloaded the footprint from? We'll take a look and get the page updated. The datasheet shows the correct dimensions with a distance of 0.65mm between the pins. Is it possible that there are a…
