ADI is a big leader in data converters area since they are investing all their money on this not like TI or national instruments. Probably they have the highest speed ADC's compared all other companies.
Wow, ADI is way ahead of competitions! Its sales is almost half of the market revenue and much larger than the closest competition. Even after TI acquires NS, TI still can come close to ADI a little. What a giant data converter vendor!
