The AD7893-2 converter has a specification on the bottom of the second page of the datasheet giving a Vdd of 5V, and under comments says "+/-5% for specified performance."
I am curious what performance degrades when the part is ran outside…
All part numbers can be found on sample and buy section
Probably the exact part number for what you want is AD7893BRZ-5.
对于ADC 12bit 8pin脚的产品，您可以考虑AD7893、AD7895（但是这两款都是外部参考）；AD7896是内部参考。
Thanks a lot for your information about AD4003+LTM2893.
Could you have any information about whether AD7983 is compatible with the LTM2893, i am considering using AD7983 with LTM2893 because i have used AD7983 in my prototype design.
