Vinh/Vinl of AD7476A and AD7476B

Hello,

I have a question about logic voltage of AD7476A and AD7476B.

http://www.analog.com/en/analog-to-digital-converters/ad-converters/ad7476/products/product.html

Pls tell me the Vinh & Vinl when using VDD = 2.5V.

The data-sheet does not describe it. Pls refer to page3.

It would be greatly appreciated if advice could be gotten.

Best Regards,

    Hello,

    Unfortunately we haven't specified Vinh and Vinl specifications at VDD of 2.5 V but please be aware that these are CMOS logic voltage thresholds therefore:

    At 2.5 V VDD the logic output specifications won't change therfore Voh and Vol are VDD-0.2 and 0.4 V respectively.

    Logic inputs, Vinl should be 0.4 V and Vinh around 1.8 V - 2.0 V.

    This device was successfully connected to the FPGA device supplied with 2.5 V without any difficulties.

    Regards,

    Jakub.
