how to ad7730
i really dont know why this error happened
if any body now more help me
i know that we lost our position in reading function
that this matter happened with nose in clk pin
i add capacitor in this line and this matter decrease my error
i make better my supply voltage and this...
connect ad7730 to atmega8
there is 2 matter
U speak about noise
i connected clk pin to avr
and this pin in avr is output
i cant see where the noise come from ?
2- why analog device not paid attention to this matter - analog device is very good company
3- this problem are exist in all off...

hi
really thanx for this
"Try with 100pF between CLK and GND"
BUT WHY
this problem is really funny for me
why this occur happened
ad7730 problems
hi again
thanking you for your attentions
1- i connected unused pins to ground
2- i see that 7710 is better than 7730 and now i try to use it but this problem is really bigger than this matter
because i designed again and again too many circuit but now i cant use this simple...

hi again
at first i used spi routin in codevision wizard
then i think maybe my problem happened from spi function
and changed my code from spi routine to manual function
but my problem not solved yet
about cs
in my code defined by cs_pin name
after reset the 7730 at the first...
problem using ad7730 and cs
i have big problem with 7730
i use ad584 for ref(+)
and Laboratory digital power supply 12v and 7805 regulator with 1u tantal cap for 5v
but 7730 work good for random second soddenly jump (for sample from 1000000)
and after it zero point losted and work for some...
