GENERAL DESCRIPTION

The AD9430 is a 12-bit, monolithic, sampling analog-to-digital converter (ADC) optimized for high performance, low power, and ease of use. The product operates up to a 210 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) and reference, are included on the chip to provide a complete conversion solution.
