AD9283 8位、50 MSPS/80 MSPS/100 MSPS ADC

AD9283: 8位、50 MSPS/80 MSPS/100 MSPS ADC

AD9283 功能框图 AD9283是一款8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。该ADC只需一个3.0 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。编码器输入为TTL/CMOS兼容。可通过进入省电模式,将总功耗降至4.2 mW。在省电模式下,数字输出被置为高阻状态。AD9283采用先进的CMOS工艺制造,提供20引脚表面贴装塑料封装（SSOP）,额定温度范围为-40°C至+85°C工业温度范围

The AD9283 is an 8-bit monolithic sampling analog-to-digital converter with an on-chip track-and-hold circuit 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.

The ADC requires only a single 3.0 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 encoder input is TTL/CMOS-compatible. A power down function may be exercised to bring total consumption to 4.2 mW. In power down mode, the digital outputs are driven to a high impedance state.Fabricated on an advanced CMOS process, the AD9283 is available in a 20-lead surface mount plastic package (SSOP) specified over the industrial temperature range (-40°C to +85°C).
