The AD9433 is a 12-bit， monolithic sampling analog-to-digital converter （ADC） with an on-chip track-and-hold circuit and is designed for ease of use. The product operates up to a 125 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband and high IF carrier systems. The ADC requires a 5 V 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 3.3 V or 2.5 V logic. A user-selectable， on-chip proprietary circuit optimizes spurious-free dynamic range （SFDR） vs. 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 userselectable for offset binary or twos 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.
