Hi Davide.
I have seen similar issues, and come to the conclusion that DAC8775 is quite sensitive against surge. You could consider using lower voltage TVS. While you are not using the tracking mode of the DAC, and are fixed at +/-15V you could go as…
Part Number: DAC8775 Tool/software: Hi,
We use the DAC8775 in our PLC AO-module project.
Now we test the Settling Time of DAC8775 but the waveform is about more than 1ms, it is slow that it is only 15-30us in the datasheet, please kindly review our schematic…
Part Number: DAC8775 Tool/software: Hi team,
I am using DAC8775 for a product that's under development.
Steps followed to configure DAC8775:
1. Reset Register(0x01) = 0x0001;
2. Reset Config Register(0x02) = 0x0012;
3. Select Buck-Boost Converter…
Part Number: DAC8775 Tool/software: Hi,
I'm trying to program the DAC8775. I followed the setup guide exactly like Brian did, but I ended up with an output of 0V, with a lot of noise.
Status Register returns meaningful values and when I write in…
Zoey,
I think short answer is that you can use the DVDD to power two ISO7641 devices. However, there are limitations to that.
The ISO7641 current consumption depends on the data rate and how much capacitance the output is required to drive. If the capacitance…
Part Number: DAC8775 Tool/software: hi team,
my customer is using DAC8775 and what will happen when we power DVDD after AVDD ? because the DVDD is gotten from the LDO supplied by AVDD.
I noticed that if DVDD applied first, it can reduce the output transients…
Part Number: DAC8775 Other Parts Discussed in Thread: DAC8760 , Tool/software: Hi TI Team.
When trying to detect open circuit in current mode output, it appears that the ALARMn output is asserted only when the current setting is greater than some 18mA…
Part Number: DAC8775 Hi team,
We used DAC8775. For /LDC signal, we use it in Synchronous Mode now.
DAC8775 Datasheet said, if certain delay “SYNC rising edge->LDAC falling edge” 33ns is not met, invalid data will be loaded. How about the invalid data…
Part Number: DAC8775 Hi team，
We are currently using DAC8775 and the Reset pin remains high when powered on. When I read the Device ID, it is 0x0003. Why does the value of this register change? Will the registers of DAC8775 be confused when the Reset…
Part Number: DAC8775 We are using DAC8775 in our new product that is under development. We have the following questions with this device:
1. With the range of 0 ~20mA of this device, is there any offset at the low end ( 0mA ) ? if it might have some offset…
