Part Number: DAC084S085 Hi,
I know that DAC084S085 has VA and VREFIN and VREFIN can be power-up with tieing VA or after VA. Then is there any rise time requirement for VA and VREFIN? Or it there no requirement and so too fast and slow rise time can…
Hi, it effectively was an SPI issue, I saw on the datasheet that data was synchronise with the falling edge, but did not pay a lot of attention because I was getting stuff working...
So, setting my SPI to MODE 1 solved the issue.
Thanks every…
Part Number: DAC084S085 Hi,
I found following explanation that SYNC and DIN buffers draw more current when they are high. Then the customer would like to know the estimated supply current or supply power at both SYNC and DIN are high. Can I refer the…
Part Number: DAC084S085 Hi,
We can see the internal 2.5k and 100k pull-down on VOUTx at block diagram but there is no description. Can you explain the purpose of these pull-down and why there are two difference value?
Best Regards,

Other Parts Discussed in Thread: DAC084S085 Hello,
I have some troubles when trying to use DAC084S085 in board.
The output is always zero whatever I do.
I am writing spi register as advised in datasheet, but nothing helps, and the output keep…
Other Parts Discussed in Thread: DAC084S085 Hola,
DAC084S085 has four control bits and they are A1、A0、OP1、OP0.
And I saw the description of the OP1 and OP0 below in datasheet：
My question is that what the different of the output between of them…
Other Parts Discussed in Thread: DAC084S085 I am not sure if this is the right forum for this question but I figured i would put it out there just in case. I am working with a DAC084S085 digital to analog converter. It is a 4 channel DAC, but I am using…
Other Parts Discussed in Thread: DAC084S085 Team,
I'm using the DAC084S085. It is a 4 channel DAC and we are only using 3 channels (A,B and C).
Channels A and C seem to work fine as long as Channel B is set to zero. If Channel B is set to anything…

DAC084S085 -Requirement specifications to the reference-
In the data sheet, LM4130, LM4050, LP3985, LP2908 reference, such as has been introduced.
For obtaining the performance of the DAC to…
In the data sheet it indicates that the DAC voltage settings are set to 0 volts at power on. It doesn't specifically say what the output termination switches are set to. Are they set to connect to the D/A buffer, 2.5k, 100k, or high impedance conditions…
