Overview
The AD9444BSVZ-80 is a 14-bit monolithic analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is optimized for power efficiency, small size, and ease of use. It features an on-chip track-and-hold circuit and operates at conversion rates of up to 80 million samples per second (MSPS). The ADC is particularly suited for multicarrier, multimode receivers, such as those found in cellular infrastructure equipment. It requires 3.3 V and 5.0 V power supplies and supports low voltage differential input clocks for full performance operation.
