AD9446BSVZ-100:  16位、80 MSPS/100 MSPS ADC

The AD9446 is a 16-bit, monolithic, sampling analog-to-digital converter (ADC) with an on-chip track-and-hold circuit. It is optimized for performance, small size, and ease of use. The product operates up to 100 MSPS, providing superior SNR for instrumentation, medical imaging, and radar receivers employing baseband (<100 MHz) IF frequencies.

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.

Optional features allow users to implement various selectable operating conditions, including data format select and output data mode.

The AD9446 is available in a 100-lead surface-mount plastic package (100-lead TQFP/EP) specified over the industrial temperature range (−40°C to +85°C).

AD9446是一款16位单芯片采样模数转换器(ADC),内置一个片内采样保持电路,专门针对高性能、小尺寸和易用性进行了优化。该产品的采样速率高达100 MSPS,具有出众的信噪比(SNR),适合采用基带中频(<100 MHz)的仪器仪表、医疗成像以及雷达接收机应用。

该ADC要求采用3.3 V和5.0 V电源供电及低压差分输入时钟信号,以便充分发挥其工作性能。对于大多数应用来说,无需外部基准电压源或驱动器件。数据输出为LVDS兼容(ANSI-644)或CMOS兼容,且包括能降低短迹线所需总电流的方式。

同时提供一些可选特性,供用户按照工作条件进行不同的选择,包括选择数据格式和输出数据模式。

AD9446采用100引脚表面贴装塑料封装(100引脚TQFP/EP),额定温度范围为−40°C至+85°C工业温度范围。
