GENERAL DESCRIPTION

The AD9444 is a 14-bit monolithic, sampling analog-to-digital converter (ADC) with an on-chip, track-and-hold circuit and is optimized for power, small size, and ease of use. The product operates at up to an 80 MSPS conversion rate and is optimized for multicarrier, multimode receivers, such as those found in cellular infrastructure equipment.
