I see in the Recommended circuit schematic for the ADAS3022 ADC that the ADR434 is to be used for providing the 4.096 V reference voltage. When I considered the ADR434 datasheet, I see that it is meant to operate at a voltage from 6V-18V. The Recommended…
Zuzuna,
I would use the ADR434. It's my favorite reference because it brings out an internal node, COMP,
allowing you to over compensate the loop and avoid noise peaking. See the "high frequency noise"
write up in the apps section of…
Hi Jonathan,
We have two AD7767 in our application and want to use one reference only.
Figure 46 in the Datasheet Rev.0 is differ to Datasheet Rev.C.
Can the reference ADR434 drive 100μF ?
Should a separate reference be used for each AD7767 or is…
Hi Rejesh,
On page 12 of the AD7626( Fig 17,19 and 21), shows the performance(THD,SNR,SINAD) of the AD7626 when using external and internal reference.
While one of the advantage of using internal reference is that there is less use of external components…
What are the recommended ADC driver, external reference and reference buffer options?
The ADAS3023 datasheet recommends the ADA4841 and AD8031 as ADC driver (to drive auxiliary input pair - AUX±) and reference buffer, respectively. Other choices…
Kris,
This seems to have solved the problem! I have been doing this on a PCB but luckily the AD8031 footprint allowed a 0R bridge directly to the ADAS3023. Before making the bridge, I was getting 4.096V from the ADR444, and after the connection, I was…
这个芯片(AD9833)的名字我猜的,可忽略看,如果是这个芯片,左看右看也不知是干吗呢?
看看截图：
HI,
I use your company's typical circuit AD8251+AD8475+AD7982 applied to multi-channel acquisition.
1.The test attachment figure. when the AD8251 input +5V, gain1, AD8475 input +5V, the AD8475 gain is connected to the IN0.4X pin, the AD7982 output…
