Hi Mark
Thank you for your support!
AD5762R has precision reference inside.
so it needs a time for stabilizing , I think.
You said RESET signal relate for power-on-time of device.
so AD5762R needs to wait for 80mSec or more after RESET changing.
I am using the AD5762R in a design and have them populated on 4 boards. The output range should be +/-10V, but on 3 of these I get a limited range of -10V to ~+7.5V on both A&B channels. The DAC on the 4th board works properly. These were all bought…
请教AD5762R的寄存器如何配置？根据手册上时序配置好后，输出没有信号？请问如何解决？
是自己搭的测试电路，SPI速率1MHz，开始以为芯片坏了，换了一块芯片，还是出现这个问题，请问怎么解决？
Hi,
Crosstalk on the AD5762R is very small compared to your measurements. AC crosstalk is -2nV-sec DAC-to-DAC, meanwhile DC crosstalk is +/-2uV. Do the crosstalk on Channel 1 disappear after some time and settle to zero volts or does it stay to the values…
Hi MASK-J,
Are you referring to the AD5762R? If so, ADI cannot guarantee that the part will be functional if the AVSS supply requirement is not met. If you wish to work with a DAC that have a single supply operation, you may want to take a look at this…
Dear Colleagues,
Is the external reference voltage applied to REFA and REFB pins of AD5762R DAC amplified x2 inside the chip before applying to the internal R-2R DACs?
To make it more clear: let's assume that AD5762 has +-15V analog power supply and…
Can you confirm what happens if /RSTIN and /RSTOUT are connected together. They are shorted together, but what happens G1, G2 and Vout?
Also, what voltage can /RSTOUT vary from and do you have any graph to show this in relation to /RSTIN for example…
