HI Chirag,
Below is a link with a list of the existing current transmitter reference designs; there a few designs that may be of interest, or provide circuit blocks / design ideas.
[FAQ] Are there reference designs that can help me build a 4-20mA…
Hello Ahmed,
Thank you for getting back to me. Can you clarify and confirm the following...
Each isolated 4-20mA output ports can either be powered externally, by an end user supplied voltage of 24 VDC at 600 W maximum, or internally, via the AC wall…
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…
To find reference designs leveraging the best in TI technology – from analog and power management to embedded processors, visit https://www.ti.com/reference-designs/index.html . All designs include a schematic, test data and design files.
I will link…
Eddie,
If the POC bit is set to 1, then the IOUT_x and VOUT_x are set to HIZ at power up, hardware and software reset. It should not affect the output when the device is in operation.
For VOUT, adding an extra 100kΩ as load should not be a problem…
Hello Hiroshi-san,
I received your PM and sent an email to the address you provided. We can continue to discuss on this E2E thread or over the email, whichever you prefer.
If PVDD/AVDD drops to this low below the recommended minimum operating voltage…
