Part Number: DAC8734 Hello guys,
Do you have at your disposal any generic DAC IP core (vhdl/verilog) I can use to drive my DAC8734? (FSM, Serial interface...).
I'm not an hdl expert so it would be great if you could provide me with anything to start…
Part Number: DAC8734 Team,
-Could you please clarify the function of the GPIO. What is the typical use case? -Is it better to provision the design to enable the use of the GPIO "in case of"? For example can it be used for debug purpose? -When GPIO will…
Hi Uttam Sahu,
I will raise the separate request regarding the daisy chain circuit of DAC8734. But before that could you please clarify whether DAC8734 support the daisy chain mode for data transfer?
Because we are planning to use two DAC8734 with…
Hi Yelsing,
I can be very difficult to determine if a device damaged by such a transient, but I think we can try some experiments with the SPI first.
Firstly, the SPI transaction you are sharing is not compliant with the DAC8734's timing diagram.…
Part Number: DAC8734EVM Other Parts Discussed in Thread: DAC8734 Hi, I have purchased two DAC8734EVM modules and have (almost) the same problem with both.
The first draws too much current (I've set the output on my power supply to max 50mA) from AVdd…
Other Parts Discussed in Thread: DAC8734 , DAC7716 I was having trouble with the DAC8734 experiencing serial data corruption until I changed my serial data timing to also surround the leading clock edge. The corruption would include having DAC-0 data…
Hi Braian,
The Basic Application Example -Figure 44 is just trying to show the various reference and gain configurations that could be used in an application. If you would like to have all for channels in the same configuration (0-5V) you can use a…
Other Parts Discussed in Thread: DAC8734 , DAC9881 I would like to use the DAC8734 to generate a +- 5V bipolar output signal into a 50Kohm load. I would like to use +- 6VDC supplies for AVDD and AVSS. Will the DAC8734 deliver +-5V into the 50K load with…
Hello Jakub,
Thank you for sharing the illustration, your proposal is clear now.
I would suggest that you stick with your gut and go with the design that is shown in Scenario B. The reason I suggest this is because if you use this approach then the…
Hi Mark,
I have not observed this on this device, but I can't guarantee that there won't be permanent damage. Usually all the problems are fixed by power cycling the device.
