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…
What is the difference between the AD5755, AD5757, and AD5755-1?
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.
Could you helps to check whether hardware reset and software has the same result for AD5757 chip.
What is the different of them.
In my testing, bot hardware and software reset can work well.
Also, in datasheet, it say that " when power up, make a…
