Part Number: DAC8742H Hi
We are using DAC8742H HART modem to transmit and receive HART signal. We need to implement HART interface for 16 channels. So we are using CD74HC4067M96 as 16:1 Mux and Demux to transmit and receive HART signals using a single …
Part Number: DAC8742H Other Parts Discussed in Thread: DAC8740H Hi
Can you please let me know the HART protocol version used in DAC8742H Hart Modem.
Also please share any reference analysis sheet for external filter design of DAC8742.
Thanks and Rega…
Part Number: DAC8742H Customer is having issues reading from the Rx FIFOs over SPI when using the DAC8742H in HART mode, although they appear to be able send data to the Rx FIFOs and initiate a HART transmission.
In there system, the SPI clock is ~500kHz…
Part Number: DAC8742H Hi,
1. DAC8742HPBS Supports daisy chain mode? As I want to interface 16 DAC8742HPBS. But in my MCU only one SPI available.
2. Do you have any SPI timing analysis data for to know how much total time SPI transaction will take by…
Part Number: DAC8742H Hello,
I have a design that has two of the DAC8742H HART modems connected to the same SPI bus. The issue that I am having is that the second IC is causing the amplitude of the SDO signals (MISO) from the first IC to be reduced to…
Dear Joseph,
Yes I think you're correct. There is some contention between these outputs (USB2ANY and USB to Serial) and cause signal disruptions.
Here's the signal when I try send the data via GUI.
Here's the signal USB to Serial TX pin output …

We're currently using the XTR115 current loop transmitter in several of our products. We're now in the process of implementing…
Part Number: DAC8742H Other Parts Discussed in Thread: TIDA-060020 Hi,
We are using DAC8742H HART Modem with 4-20mA receiver circuit.
The HART Output is coupled to the 4-20mA analog input circuitry.
We are referring TI Designs: TIDA-060020.
In this application…
Part Number: DAC8742H Other Parts Discussed in Thread: PROFIBUS , , We want to use both HART and profibus /Fieldbus with DAC8742H. As per my understanding only below hardware changes are required to use both protocols. Please confirm.
HART
Profibus…
