I am using AD8475 in one of my application:
http://www.analog.com/static/imported-files/data_sheets/AD8475.pdf
It says it has attenuation of 0.4 & 0.8.
Page 21 shows a diagram in which +-10V signal gets attenuated to +4V signal (reference above +2.5V).
Now my question is when signal is +10V, output is 4.5V. This make a amplitude of 2V, since signal is riding over 2.5V.
So +10V gets attenuated to 2V, so doesn't that it mean signal gets attenuated by 0.2 but datasheet says it has 0.4
