Use the AD5757 sample two.Circuit in accordance with the "UG-244.pdf" in the manufacture of circuit PCB. All register reads and writes are correct. Select the OUTEN bit to enabled,Output current measurement results only programmed current value of the…
Blue line: CS
Purple line: CLK
Green line: DIN of AD5757
Yellow line: Dout of AD5757
What is the difference between the AD5755, AD5757, and AD5755-1?
可以使用AD5757 或者 AD5755
1- I do not want to use Dynamic Power Control in AD5757 and AD5755. Can I connect my 12 volt to Vboost or only min voltage is 15 volt.
2- In AD5755 can I do not connect AVss to -volt And the Vout_x is only 0-5 or 0-10 volt.
SDO from AD5757 (J11) is connected to MISO pin on master board.
"输出端开路时二次电流大" 表示什么意思呢，最好贴一下电路， AD5757的输出电流为4-20mA
Thanks for your feedback. The transistor should be a PMOS.
The AD5757 board had used a NTLJS4149PTAG but this is now obsolete. We plan to use the FDMA530Z in future boards instead.
