AD9461:  16-Bit, 130 MSPS ADC

The AD9461 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 130 MSPS, providing superior SNR for instrumentation, medical imaging, and radar receivers employing baseband (<100 MHz) and 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 CMOS or LVDS compatible (ANSI-644 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 input range, data format select, and output data mode.

The AD9461 is available in a Pb-free, 100-lead, surface-mount, plastic package (100-lead TQFP/EP) specified over the industrial temperature range −40°C to +85°C.

AD9461是一款16-bit单芯片模数转换器,内置跟踪保持电路。AD9461针对高性能、小尺寸以及易用性而优化。产品的采样速率高达130 MSPS,具有出众的信噪比(SNR),适合工作在基带(<100 MHz)与IF频率的仪器仪表、医疗成像以及雷达接收机。

AD9461采用3.3 V或5.0 V电源供电,根据性能运行的需求,要求低压差分输入时钟信号。对于大多数应用来说,无需外部基准电压源或驱动器件。数据输出符合CMOS或LVDS标准(符合ANSI-644标准)且包括均值,能降低短跟踪距离所需的全部电流。同时提供一些可选特性,以供用户按照工作条件进行不同的选择,包括输入范围、数据格式选择以及输出数据模式。AD9461采用100引脚无铅表贴塑料封装(100引脚TQFP/EP),工作温度范围是:-40°C~+85°C。
