Integrated Device Technology
ADC0808S125/250
Single 8-bit ADC, up to 125 MHz or 250 MHz
The total intermodulation distortion is given by:
IMDdB
=
10
l
o
g10
P---P-i--n-s--ti-e-g--r-n-m-a--o-l--d
where:
Pintermod = ai2mf1 – f2 – ai2mf1 + f2 + ai2mf1 – 2f2 + ai2mf1 + 2f2 +
+ ai2m2f1 – f2 + a2im2f1 + f2
where a2imfn is the power in the intermodulation component at fn.
