You can connect 4 x AD5270 modules, you will need to send 16 x 4 = 64 bits.
Lets say we have 4 AD5270 digiPOTs ( U1, U2, U3, U4),
U1 ->DCEN-> U2 ->DCEN -> U3 ->DCEN -> U4
The first 16 bits you send goes to U4, Next 16…
Thank you for your answer. Our customer tried it, but AD5270 was no responding. On the other hand, the customer tried to change the timing of the SPI.
The following is NG case;
And the following is OK case;
I can't find the timing specification…
thank you msamera,
may i know the responds of AD5270 ,upto the range of 100Khz? you and the datasheet revealed the 1k range.
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…
I'd like to avoid mechanical trimmer for adjusting the output voltage.
Is good idea use Digital Rheostat AD5270 in Trim circuits or noise and thermal drift digital potentiometer completely kills accuracy ADR44x?
In ADI, we define code loss as the range of codes which are having the resistance tolerance above or below a certain percentage. In the case of AD5270, the resistance tolerance for the code loss is ±1%.
