AD9284BCPZ-250 Datasheet PDF - ADI

●Product Details

●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.

●PRODUCT HIGHLIGHTS

● 1. Integrated dual 8-bit , 250 MSPS ADC.

● 2. Single 1.8 V supply operation with LVDS outputs.
