I want to connect multiple AD7779 SDOs together.
When in SPI mode, does SDO operate as tristate? i.e. SDO is high impedance when the device is not selected?
Hello, I'm using AD7779, now I have a problem:
here below are my datas got from ad7779,but I don't known how them mean, which channel ,and what's the Decimal data of them ?
There is some literature about ground planes on the web, have a look to these below:

Hi, you've previously answered a question about using SPI to configure AD7779s which are connected in Daisy chain and have confirmed that this is possible.I'd like to check/confirm one thing though... table 38 (and fig116) says Format0 should be…

While planning to use the internal reference of the AD7779, I left unconnected the REFx+ and REFOUT pins (and connected the REFx- to AVSS). Tha ADC looks to works fine, but i experience a very large level of input refered noise.
Looking back to the datasheet…
I found MEMMAP_CRC_ERR Error after checking the register of AD7779.
So, I supplied the 100 ms reset pulse after the power supply.
However, it is still in error.
After clearing the MEMMAP_ CRC_TEST_EN bit, the error condition was disappeared.
Please show me step by step how to calculate the temperature ADC7779 in celsius degrees.
When i read register CH0_ERR_REG,i found that:
a、CH0-AINP undervoltage error,CH0-AINM undervoltage error，how can i deal these errors？
