The AD9229 is a 50 or 65 MSPS quad 12-bit, analog–to–digital converter with serial LVDS outputs. An on–chip track–and–hold circuit is designed for low cost, low power, small size and ease of use. The product operates up to a 65 MSPS conversion rate and is optimized for outstanding dynamic performance where a small package size is critical.
The ADC requires a single +3 V power supply. No external reference or driver components are required for many applications. A separate output power supply pin supports LVDS compatible serial digital output levels.
The ADC automatically multiplies up the sample rate clock for the appropriate LVDS serial data rate. This data clock output (DCO) provides operation up to 390 MHz and supports double-data rate operation (DDR). An MSB trigger or Frame clock is also provided to signal a new output byte. Power down is supported, and the ADC consumes 3 mW when enabled.
Fabricated on an advanced CMOS process, the AD9229 is available in a 48-pin chip scale 7 mm x 7 mm package (48-LFCSP) specified over the industrial temperature range (–40°C to +85°C).

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.
AD9229 IBIS Models
For designers who are selecting or evaluating high speed ADCs, VisualAnalog™ is a software package that combines a powerful set of simulation and data analysis tools with a user-friendly graphical interface.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
