GENERAL DESCRIPTION
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 are required for many applications. The digital outputs are LVDS compatible.
The AD9284 is available in a Pb-free, 48-lead LFCSP that is specified over the industrial temperature range of −40°C to +85°C.
