Ibrahim,
The setup for the transmission of the PAFF data is done through a four byte sequence as described in section 7.4.2 in the datasheet that describes the UART interfaced PAFF communication. The four bytes are shown in a diagram of the bytes and…
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…

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 need for…
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, we would…
Part Number: DAC8742H Hi !
We are using the DAC8742H in HART mode and have configured XEN, CLK_CFG0 and CLK_CFG1 to accept an external CMOS clock source (generated with a function generator) running at 3.6864 MHz (line 1 in Table 1 on page 16 of the data…
Joseph-san,
My customer want us to suggest(not guarantee) a protection circuit for DAC8742H against IEC61000-4-4 and 4-5.
Could you suggest an example circuit?
Datasheet typical application circuit has 40V TVS, ferrite beads and 1000pF capacitor.
What…
Part Number: DAC8742H I'm using the dev board connected to an 8 bit processor via SPI. I'm able to inject a ten byte HART string of the following bytes: 0xFF 0xFF 0xFF 0xFF 0xFF 0x02 0x80 0x00 0x00 0x82. The Rx FIFO buffer Level is set to 1, and…
