Does the SCLK have to be continuous for the AD7321?
Hi,
I made some study for AD7321 for a while and I thought this chip could meet our requirement. But when I tried to purchase the evaluation board to perform a further evaluation, the system said that EVAL-AD7321 was not recommended for new designs and…
hi, Sir:
The datasheet says that:
Resolution:
Differential mode: 12-bit plus, sign (13 bits)
Single-ended/pseudo differential mode: 11-bit plus, sign (12 bits)
I always get the 12-bit plus, sign (13 bits) in either mode.
Is it right? thanks.
Is it possible to make driver for AD7321 with IIO framework..?
I found out Industrial Input Output (IIO) framework driver for most of ADCs.
But i cant able to find out IIO driver for AD7321.
Can any one help for me..?
For most of other ADC devices, IIO ( Industrial Input Output) is available.
But i can't able to find out IIO driver for AD7321.
But i got only AD7321 Evaluation Software from http://www.analog.com/en/products/analog-to-digital-converters/ad-converters…
问题1:我公司使用AD7321芯片过程中发现容易出问题,不确定芯片是否已经坏了,因为芯片还是有输出信号,不过输出信号和正常工作时不一样,当输入信号有变化时,输出信号也有变化。怀疑是芯片初始化问题,但是重新初始化还是不能正常工作。同一个程序,更换芯片后就正常工作。
问题2:AD7321 DOUT示波器测量信号时发现,DOUT数字脉冲信号最后一个bit跟电平0位不是垂直的,而是斜线向下到达零位的。

工程师你好:
你好, 我正在使用贵公司的AD7321芯片, 现在想用ARM9的Linux系统通过SPI读取芯片数据, 想问一下您那有没有开发好的驱动程序和测试应用程序。希望能够尽快回复,谢谢!
for AD7321 when it is single-ended mode, the output is 12bits,
My concern is when in single-ended mode, which bits are useful in the first figure? sign bit + DB11-DB1 or DB11-DB0?
Looking forward to your answer.
Thank you very much!
我的情况是,只使用IN0测量信号,并连续测量,输出编码格式为直接二进制编码,CONTROL REGISTER为0x8038,RANGE REGISTER为0xA000,下图分别为示波器测得的写入信号和始终,频率为300khz。但是,不知道为什么,我的芯片输出端没有信号
