Part Number: DAC1220EVM Hi
I wonder why DAC output voltage can not reach at 5V under certain conditions.
I use self-calibration function.
The conditions are as follows.
1) Provide analog voltage under 5.02V
2) At low temperature( -30'C > T )

Part Number: DAC1220EVM Hi all,
My customer tried to evaluate DAC1220EVM with MMB0 on DXP software. After installing DXP software, my customer connected PC and DAC1220EVM thru USB. And they run DXP software. DXP did not find the DAC1220EVM. So DAC config…
Part Number: DAC1220EVM HI,
When I lauched dac dxp program, it showed that "error -1073807343 DXP_main.vi VISA State - load Firmware Load"
How should I deal with that error? The program cannot run before fixing that issue.
Thanks!
Part Number: DAC1220EVM Hi all, My customer reported that it seems MMB0 does not output the SPI signal to DAC1220EVM. Could you tell me the procedure to solve it? EVM settings are as follows;
MMB0 (Rev C): - DC 6V -> J2 - J12 -> Short - J13: +5V…
Part Number: DAC1220EVM Hi,
I am new to using the DAC1220 EVM hence apologize if I have over-looked any obvious information.
I am looking to programmatically generate waveform from the DAC EVM using SPI and came across "DXP DAC exerciser program" which…
Bob,
I finally got the DAC1220EVM module to work. I could not get it to work using chip select as it would give me unreliable results. I went through all the timing diagrams and verified my timing and still it would not work until I tied chip select to…
There is another thread looking in to this right now. Let's focus on that that thread and close this one.

Also as additional question about the DAC1220. What value have the SNR? A more general question: Which EVM board has lower noise for a DC output? The DAC1220EVM or the DAC8831EVM? Our customer project need a simple DAC. The DAC is used to set a constant limit…
Hi Ahmet,
Thank you for the additional information and schematic for the gain amplifier stage, below a couple of general comments, although the queries are more related to a battery tester:
Regarding the stability of the loop: I have not performed a…
