To drive this ADC in DC-coupled applications, we suggest ADA4938-1. To drive this ADC in AC-coupled applications, we suggest AD8352.

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 thermally enhanced 52-lead plastic quad flatpack specified over the industrial temperature range (-40°C to +85°C) and is pin-compatible with the AD9432.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).

The package for this IC (i.e. DIP, SOIC, BGA). An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
