AD7327 can be interfaced with 8Bit SPI Microcontroller Port?

Hi

1. I wanted to know the max supply current for +-15V supply input for AD7327

2. If I don't use a power sequencer for the chip and use the recommended BAT34 schottky diodes only, would it work?

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,

Please give me more information about the AD7327 temperature indicator.

- What is the purpose?
  Are there the application examples?

- The datasheet describes only Figures 46/47 for specifications.
  Is there other information?
  Conversion equation…

I will use the ADC AD7327 (8 channel, Software-selectable input range)

The ADC is powered with +-15V and the signal input range should be set to +-10V.
What happens if the input signal voltage is outside the set measuring range?
So between +10V to +15V or…

我单独在AD转换芯片加稳定直流电压，转换结果正常。但是将模拟输入端接入经传感器过来的模拟信号时，AD7327转换后的数字量一直为0FFF，我用示波器看了输入电压没有超量程（正负10v）。这是什么原因呢？？？求指教！！！

Hello,

We can see some ADC errors on the page 4 in the datasheet of AD7327. Do the specs include an impact of Reference output voltage error (+/-10mV)? Or should we independently count the effect of the Reference output voltage error as those specs for…

I have a question about Figure 46 in the AD7327 datasheet , Rev B .  Our application also uses +/10V range, but our Vcc is 3.3V, not 5V as in said figure.  How does the curve/equation change for Vcc = 3.3V?    Somehow, our software team is using this equation…

Hi,

Can you please explain why Schottky diodes are recommended to be connected to VDD and VSS pins of AD7327.
