FAQ
Hello,
For circuit reasons, we are using the AD5271 with a voltage of Vdd:3.300V and Vss:-1.720V.
We are using only RAM because writing to ROM does not work well, probably due to Vss.
I am using RAM only.
So, please tell me about the following.

Hi,
Before create this thread I tried different SPI command sequence in order to update the resistor of the AD5271.
Currently I am doing the following:
AD5271 connected to a FPGA.
CPOL => '0'
CPHA => '1'
SCLK frequency 200…
Hi all,
I am asking about the SPI timing of the AD5270/AD5271 for write operation.
Please tell me about tRDAC_R - PERF and tRDAC_NORMAL written in the data sheet.
We thought as follows:
Which is the right choice?
①Write command execution time of RDAC …
想问下在菊花链操作(两个电位器芯片)中,可以正常写指令,但是读指令的话,SDO返回的数据都是第一个芯片的数据值,菊花链方式下如何读操作?
请大神指点,谢谢。
Hello,
I got some point out about AD5270/AD5271 datasheet.
It seems not "Table 13" but "Table 15" at below passages.
1) 3rd and 8th lines at 50-TP MEMORY BLOCK on page 18
2) 10th line at RDAC AND 50-TP READ OPERATION on page…
