Part Number: DAC161S997 Other Parts Discussed in Thread: TIDA-00648 Hi, Let me confirm about below. * According to datasheet, this device has "HART injection" function via "C2" pin. However, I'm not sure this function work as "HART input" or "HART output…
Part Number: DAC161S997 Other Parts Discussed in Thread: TIDA-00648 , , Dear ,
We are using loop power 4-20mA transmitter. we are referring below 2 circuit reference,

Hi
sorry I made a mistake,
In my last reply, I made a mistake in one of the places, which should be TIDEP-0091 and TIDA-00648, the two design references, where TIDA-00648 is (4-20mA current loop transmitter reference design)
Thank you

Roberto,
I don't know if we have the original source for the DAC161S997. However, there are several example TI designs that use the DAC161S997 as a loop controller and have some firmware written for some of our MSP430 devices. You can find these designs…
Hi Gary,
I do not believe the EVM firmware is available but we have a couple of reference designs with DAC161S997 + MSP430 that include the firmware:

Hello,
The software for TIDA-00648 was written for MSP430F5172. I am not sure if it is compatible with the devices you have tried without some modifications as these are pretty different architectures overall.
Thanks,
Garrett
Thanks for your response. I wanted to attach the schematic but struggling to do so. Same as the c code but is a zip file from under software.
The mcu i am using is ATSAM4CMS from atmel/microchip ( ).
I am using my own hardware but picked a lot from…
HI Shinu,
thanks for contacting us via e2e regarding this customer inquiry. Please find my answers below.
1) An open circuit is detected by reading 0V (due to 0mA) from the shunt. This violates the requirement of having at least a 4mA current and…
Have you measured the voltage of the input pin for variance when the ADC is operational? You may require a voltage follower or other external circuitry to avoid impedance mismatch, among other possible issues. Have you referred to SLAY030, TIDA-00648…
