I have question regarding the analog channels of the AD7770: are the analog channels isolated in AD7770? Can they be coupled directly with signals coming from plcs? Isolation amplifiers required for AD7770 if necessary?

I have a question about a differencis of digital flter between AD7770 and AD7779.Attached file is the rms noise and resolution performance table from the datasheet.AD7779 and AD7770 have same combination of ODR and Decimation Rate excluding 32kSPS…
I'm using the AD7770 Eval Board. The Main Supply of the board is from the 9V external Wall Adapter and I want to get ADC data to Altera FPGA board through J1 header ( SPI mode)
However, after the power up the DRDY signal is always at LOW state. I…
I use the AD7770 evaluation kit and supply it with an external +9V power supply. All bridges are in the basic position, except the MAIN SUPPLY in position B and SL1 in position B.
When I measure the power supply voltages of the AD7770, I observe…

I search some example code to drive the AD7770 SPI.
thank you for your answers.
I'm using the Eval Board of AD7770.
The maximum amplitude I can measure between AIx+ and AIx- is +/- 1.65V (dual supply operation)
According to the AD7770 datasheet, he noted that the maximum amplitude is +/- 2.5V (according to table 11 of…
I would like to evaluate three ADC. THE AD7770, AD7768 and the AD7124.
The evaluation boards of the AD7770(EVAL-AD7770FMCZ) and AD7768(EVAL-AD7768FMCZ) need the Demonstration platform "EVAL-SDP-CH1Z" whereas the evaluation board of the AD7124(EVAL…
