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
- Integrated dual 8-bit , 250 MSPS ADC.
- Single 1.8 V supply operation with LVDS outputs.
- Power-down option that is controlled through a pin programmable setting.
APPLICATIONS
- Communications
- Diversity radio systems
- I/Q demodulation systems
- Battery-powered instruments
- Handheld scope meters

Tools & Simulations
Virtual Eval - BETA
Virtual Eval is a web application to assist designers in product evaluation of ADCs, DACs, and other ADI products. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, response plots, and more.
