anybody knows if it´s possible to utilize this ADC in single ended analog input configuration?
I need to sample the full 4 V input range
Thanks in advance
It is possible to use the AD9460 in single ended mode. The only problem here is that you will not get the benefit of the differential signal. this means that your dynamic range (SNR) will be reduced. I think it automatically gets reduced by 3dB per my math. Additionally you will not be able to take advantage of the noise cancelling in the differential signal. So you will have to deal with that as well. When you provide a single ended signal to the ADC, your full scale will get reduced to 2Vpp. The AD9460 is only rated up to 3.4Vpp differential. This means each VIN+ and VIN- will swing 1.7V around the common mode.
David.Buchanan has written an excellent article on how the SE vs Diff signals are interpreted in the ADC. Please see link below:
