AD9288BST-80: 8位、40/80/100 MSPS、双核ADC
The AD9288 is a dual 8-bit monolithic sampling analog-to-digital converter with on-chip track-and-hold circuits and is optimized for low cost, low power, small size and ease of use. The product operates at a 100 MSPS conversion rate with outstanding dynamic performance over its full operating range. Each channel can be operated independently.
The ADC requires only a single 3 V (2.7 V to 3.6 V) power supply and an encode clock for full-performance operation. No external reference or driver components are required for many applications. The digital outputs are TTL/CMOS compatible and a separate output power supply pin supports interfacing with 3.3 V or 2.5 V logic.
The encode input is TTL/CMOS compatible and the 8-bit digital outputs can be operated from +3 V (2.5 V to 3.6 V) supplies. User selectable options are available to offer a combination of power down modes, digital data formats and digital data timing schemes. In power-down mode, the digital outputs are driven to a high-impedance state.
Fabricated on an advanced CMOS process, the AD9288 is available in a 48-pin surface mount plastic package (7x7 mm, 1.4 mm 48-Pin LQFP) specified over the industrial temperature range (-40°C to +85°C). Pin out designed for 10-bit migration.
AD9288是一款双核8位单芯片采样模数转换器（ADC）,内置片内采样保持电路,专门针对低成本、低功耗、小尺寸和易用性进行了优化。该产品采用100 MSPS转换速率工作,在整个工作范围内都具有出色的动态性能。每个通道均可以独立工作。
该ADC只需一个3 V（2.7 V至3.6 V）单电源和一个编码时钟就能充分发挥工作性能。对于大多数应用来说,无需外部基准电压源或驱动器件。数字输出为TTL/CMOS兼容,单独的输出电源引脚支持3.3 V或2.5 V逻辑接口。
编码输入为TTL/CMOS兼容,8位数字输出可以采用+3 V（2.5 V至3.6 V）电源供电。用户可选项提供各种省电模式、数字数据格式和数字数据定时方案组合。在省电模式下,数字输出被置为高阻状态。
AD9288采用先进的CMOS工艺制造,提供48引脚表面贴装塑料封装（7x7 mm、1.4 mm 48引脚LQFP）,额定温度范围为-40°C至+85°C工业温度范围。引脚排列设计可实现10位升级。
