ADC0808S125/250
Single 8-bit ADC, up to 125 MHz or 250 MHz
The total intermodulation distortion is given by:
IMD[dB] = 10log10P----Pi--n-s--t-ie-g--r-n-m-a--o-l--d-
where:
Pintermod = a2im( f 1 – f 2) – a2im( f 1 + f 2) + a2im( f 1 – 2 f 2) + ai2m( f 1 + 2 f 2) + …
… + ai2m(2 f 1 – f 2) + ai2m(2 f 1 + f 2)
where ai2m( f n) is the power in the intermodulation component at fn.
Psignal = a2f 1 + a2f 2
