AD9432: 12位、105 MSPS ADC

AD9432 功能框图AD9432是一款12位单芯片采样模数转换器(ADC),内置一个片内采样保持电路,专门针对高速转换和易用性进行了优化。该产品采用105 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5.0 V单电源和一个105 MHz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逻辑接口。编码器输入支持差分或单端信号,且为TTL/CMOS兼容。12位数字输出可以采用+3.0 V(2.5 V至3.6 V)电源供电。AD9432采用先进的BiCMOS工艺制造,提供52引脚公制方型塑料封装(52 LQFP),额定温度范围为-40°C至+85°C工业温度范围

The AD9432 is an 12-bit monolithic sampling analog-to-digital converter with an on-chip track-and-hold circuit and is optimized for high speed conversion and ease of use. The product operates at a 105 MSPS conversion rate with outstanding dynamic performance over its full operating range.The ADC requires only a single 5.0 V power supply and a 105 MHz 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 logic. The encoder input supports either differential or single-ended signals and is TTL/CMOS compatible. The 12-bit digital outputs can be operated from +3.0 V (2.5 V to 3.6 V) supplies.Fabricated on an advanced BiCMOS process, the AD9432 is available in a 52-pin metric quad plastic package (52 LQFP) specified over the industrial temperature range (-40°C to +85°C).
