Part Number: TIDA-01504 Hello team,
My customer and I have a question on resistor value setting of R3 and R4. Do you have any advice on decide R3 (or R4) value?
We understood that large R3 / R4 value is important.

Hi , We are going to design a hardware for "Loop-Powered, 4- to 20-mA Field Transmitter With HART Modem" . I was reading the Demo version released by TI named "…
Part Number: DAC8740H There is a HART® Modem Reference Design( TIDA-01504 Highly-Accurate, Loop-Powered, 4mA to 20mA Field Transmitter With HART® Modem Reference Design | TI.com ). I want to get the Msp430 sample code in this reference design.
Part Number: TIDA-01504 We are looking at reference design TIDA-01504 and we don't understand the equation #11: Z m = R V a · V b (file is attached).
Could it be Z m = R / V a · V b ?
If yes how correct are the values Zm in table 11? tidudf6…
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 can be…
Is my following understanding correct?
-> In TIDA1504, it might be possible that MSP430FR2355 work as DAC8740H + DAC8830 + OPA333 + OPA335
Are there any possible problems?
In theory, that is correct; however, TIDA-01504 is mostly…
The HART physical layer test is a system level test of the end product (transmitter, analog input module, etc). Of course, the DAC874xH was designed to meet the HART physical layer standard, but it is not an IC level test.
We have a transmitter…
We are working on a reference design dedicated to Foundation Fieldbus, the main source of difficulty / delay with respect to when these devices released has been regarding the FF stack itself, as we did not previously have a FF stack. Right now…
