12-Bit 105/125 MSPS Analog-To-Digital IF Sampling Converter
The AD9433 is a 12-bit monolithic sampling analog-to-digital converter with an on-chip track-and-hold circuit and is designed for ease of use. The product operates up to 125 Msps conversion rate and is optimized for outstanding dynamic performance in wideband and high IF carrier systems.
The ADC requires a +5V analog power supply and a differential encode clock for full performance operation. No external reference or driver components are required for many applications. The digital outputs are TTL/CMOS compatible and a separate output power supply pin supports interfacing with 3.3V or 2.5V logic.
A user-selectable, on-chip proprietary circuit optimizes spurious-free dynamic range (SFDR) versus signal-to-noise-and-distortion (SINAD) ratio performance for different input signal frequencies, providing as much as 83 dBc SFDR performance over the dc to 70 MHz band.
The encode clock supports either differential or single-ended input and is PECL-compatible. The output format is user-selectable for binary or two's complement and provides an overrange (OR) signal.
Fabricated on an advanced BiCMOS process, the AD9433 is available in a 52-lead thin quad flat package (TQFP_EP) that is specified over the industrial temperature range of −40°C to +85°C. The AD9433 is pin-compatible with the AD9432.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
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.

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.
