Part Number: DAC8742H Hello, Does DAC8742 support "burst command" of HART communication? If it supports the command (or has an example) and depends on the software implementation, it would be appreciated if you could share some tips on how to implement…
Hi Joe
I checked the Physical Layer Conformance Test again and the test use only a single FIXED jitter pattern specified in table 6.3.3 as you said. It seems unrealistic, but this makes the test easier to pass. Using a fixed jitter pattern, I believe…
Part Number: DAC8742HEVM Other Parts Discussed in Thread: DAC8742H Tool/software: I am using two DAC8742HEVM to develop HART communication in which one serves as transmitter and the other serves as receiver. The transmitter board's MOD OUT is connected…
Part Number: DAC8742H Other Parts Discussed in Thread: DAC8740H , DAC161S997EVM , DAC161S997
Hi Team,
Please help to advise the power consumption of DAC8742H and DAC8740H.
In the datasheet, there is only statement for the external crystal, still…
Part Number: DAC8742H Tool/software: I am currently using a DAC8742H as a HART modem and was wondering about the behavior of the digital reset input. I plan to use the DAC8742H in UART mode and never change the configuration inputs (XEN, CLK_CFG0, IF_SEL…
Part Number: DAC8742H Dear TI Technical Support,
Currently we are developing instrument device with Foundation Fieldbus H1 protocol.
I have DAC8742HEVM Development Kit and I try to test the kit using DAC8742HEVM GUI Software.
In that software…
Part Number: DAC8742H Hello TI
We are developing a sensor data gathering and management system, which requires a Foundation Fieldbus Interface. Our project has a 4-20mA current loop physical layer. And it is already implemented.
In this regard,…
Part Number: DAC8742H Tool/software: I am currently using a DAC8742H as a HART modem with internal filtering, voltage reference, and oscillator. The datasheet for the DAC8742H explains that the internal filter uses less components than an external filter…
Part Number: DAC8742H Other Parts Discussed in Thread: PROFIBUS , Hi to all,
We are working with one customer who is interested in developing a device that could support all the three protocols the DAC8742H offers. This part fit perfectly in their requirements…
