General Description
AD9444 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.
The ADC requires 3.3 V and 5.0 V power supplies and a low voltage differential input clock for full performance operation. No external reference or driver components are required for many applications. Data outputs are LVDS-compatible (ANSI-644) or CMOS-compatible and include the means to reduce the overall current needed for short trace distances.
