AD9480: 8位、250 MSPS、3.3 V ADC
AD9480是一款8位单芯片模数转换器（ADC）,专门针对高速、低功耗、小尺寸和易用性进行了优化。该产品采用250 MSPS转换速率工作,在整个工作范围内都具有出色的线性度和动态性能。为使系统成本和功耗达到最低,AD9480内置了一个基准电压源和采样保持电路。用户只需要提供一个+3.3 V电源和一个差分编码时钟。对于大多数应用来说,无需外部基准电压源或驱动器件。数字输出为LVDS兼容（ANSI 644）,可选择二进制补码或二进制输出格式。各输出数据位以并行方式与LVDS输出时钟一同提供,简化了数据采集。AD9480采用先进的BiCMOS工艺制造,提供44引脚表面贴装封装（TQFP）,额定温度范围为-40°C至+85°C工业温度范围。
The AD9480 is an 8-bit monolithic analog-to-digital converter optimized for high speed, low power, small size, and ease of use. The product operates at a 250 MSPS conversion rate, with excellent linearity and dynamic performance over its full operating range.
To minimize system cost and power dissipation, the AD9480 includes an internal reference and track-and-hold circuit. The user only provides a +3.3 V power supply and a differential encode clock. No external reference or driver components are required for many applications.The digital outputs are LVDS (ANSI 644) compatible with an option of twos complement or binary output format. The output data bits are provided in parallel fashion along with an LVDS output clock, which simplifies data capture.Fabricated on an advanced BiCMOS process, the AD9480 is available in a 44-pin surface mount package (TQFP) specified over the industrial temperature range (-40°C to +85°C).
