A/D Converter

[kirk]

Hi guys!

I have to choose a A/D converter architecture for an input signal 0-2 MHz and I should get a SDNR lower than 57 dB.
Which architecture can you suggest me?

Thanks,
Kirk

The Analog Devices AD671 appears to fit your qualifications. As far as Signal to Noise ratio, your input voltage scaling and its noise component will have as much impact on the total S/N ration as anything.
