Available in 48-lead LFCSP The AD9284 is a dual 8-bit, monolithic sampling, analog-to-digital
converter (ADC) that supports simultaneous operation and is
optimized for low cost, low power, and ease of use. Each ADC
operates at up to a 250 MSPS conversion rate with outstanding
dynamic performance.
The ADC requires a single 1.8 V supply and an encode clock for
full performance operation. No external reference components …
