GENERAL DESCRIPTION
The AD9445 is a 14-bit, monolithic, sampling analog-to-digital converter (ADC) with an on-chip IF sampling track-and-hold circuit. It is optimized for performance, small size, and ease of use. The product operates at up to a 125 MSPS conversion rate and is designed for multicarrier, multimode receivers, such as those found in cellular infrastructure equipment.
