Part Number: TIDA-01504 Other Parts Discussed in Thread: DAC8740H , AFE882H1 , AFE881H1 Hi Buddy,
This design guide includes HART i/f, could you please help share the HART DLL code to support the last protocol? thanks.
best regards,
Jay
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.
Best regards,
Shotaro

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: DAC8830 Other Parts Discussed in Thread: TIDA-01504 "I need help with the grounding connection of the DAC8830, as when connecting it to a microcontroller, I experience voltage drops in VREF and CS. Additionally, Vout shows no variation. I…
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…
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 can be…
