Dear Responsible,
In my research project i used AD7328 ADC in order to readout unipolar analog signals.
SPI digital communication was isolated by using ADUM3481.
During prototyping i noticed that digital isolator was broken. After a long search period…

Hi,
I am using AD7328, AMP04 and AD5734 in design for the data conversion applications. Could you p[lease review the attached schematic and let me know if any issue is found. These are used for processing analog signals of +-15V under 500KHz.
Regards
…Wrote a code like this, but it doesn't work. What am I doing wrong? Tell me please. thanks
#define cs_low() (GPIOD->BSRR = GPIO_BSRR_BR2)
#define cs_high() (GPIOD->BSRR = GPIO_BSRR_BS2)
#define AD7328_WRITE (1 << 15)
#define AD7328_READ…

Here is my code
#define cs_low() (GPIOD->BSRR = GPIO_BSRR_BR2)
#define cs_high() (GPIOD->BSRR = GPIO_BSRR_BS2)
void AD7328_SequenceMode(void){
cs_high();

我使用SPI传输模式用mode2(CPOL=1，CPHA=0)，SCLK频率500kHz，t2 3.1us，t9、t10是1us。
下面图1，我用AD7328的pin脚接法，我用arduino传输SPI，并且用arduino的3.3V接脚供电给Vdrive、VCC，VDD和Vin用电源供应器供电。
图2，传送的指令为0b1011111111100000，设定范围。
图3，传送的指令为0b1000010000110000，读值。
我使用回圈重复传送图1与图2指令(或者1次图2，只重复图3)，读到的DOUT如图4…
Hi,
I have a question about the AD7328.
What is the allowable error for the 680nF capacitor attached to the REF IN / OUT pin?
Is it okay to attach a capacitor with a tolerance of ± 20%?
Best regards
Yuya
