Hi
As is shown above,when Vlogic and VDD supplies of 3.3 V,all the channels can output correctly except the maximum voltage is 3.2 V.However,when Vlogic and VDD supplies of 5 V,only some of the channels can output from 3 V to 4.9 V.When I send data…
In the page 15 of data sheet , upper dead band is described as follows.
DC specifications tested with the outputs unloaded, unless otherwise noted. Upper dead band = 10 mV and exists only when the internal reference voltage (V REF ) = V DD with gain …

Hi all,
how long I have to wait before writing the next command to the AD5671R?
Kind regards,

AD5764的DGND和AGND需要在尽可能离芯片近的地方连为一点接到系统的AGND上。但是这个点和系统的星型接地点不是一回事也没有直接的关系。对于伺服控制接口的DA芯片需要综合考虑所需的精度，解析度，输出路数和输出电压范围来进行选型。ADI的AD568x系列提供高性价比，单通道到四通道，0～5V输出，16位/12位解析度的DAC解决方案。AD5671R/21R提供高性价比单通道，-10V到10V输出范围，16位/12位解析度的DAC解决方案。

Q1. What is new?
A1. The nanoDAC+(TM) family offers improved analog performance in terms of INL and glitch energy specifications.. Some members of the family, those with a part number ending in 'R', for example AD5686R, include a low drift…
