Question
I have two questions about AD7705.1. Is it sensitive to high magnetic environment?One customer wanted to use it near a wire with more than 10,000A current.
2. I would like to know whether the output of DOUT is high impedance state if the chip is not selected by /CS.If so, we can connect two pcs AD7705's DOUT to only one pin of MCU?.
Answer
We have not evaluated this part in a high magnetic environment. However, a high magnetic environment may affect the conversions and the registers.So, I would advise the customer to shield the AD7705.
When CS is high, DOUT is high impedance. So, the DOUT lines of the 2 AD7705 devices could be connected to one pin on the MCU.
