AD7265是一款12位双核高速、低功耗的逐次逼近型模数转换器（ADC），工作电压为2.7 V至5.25 V单电源，最高呑吐量可达1 MSPS。这款器件内置两个ADC，两者之前均配有一个3通道多路复用器和一个能够处理30 MHz以上输入频率的低噪声、宽带宽采样保持放大器。\n\n 转换过程和数据采集过程均采用标准控制输入，可与微处理器或DSP轻松接口。输入信号在CS的下降沿进行采样，而转换同时在此处启动。转换时间取决于SCLK频率。AD7265采用先进的设计技术，可在高呑吐量的情况下实现极低的功耗。其工作电压为5 V，呑吐量达1 MSPS，而最大功耗仅为4 mA。采用正常运行模式时，该器件还具有灵活的功耗/呑吐量管理能力，这要归功于超低的静态电流消耗水平。\n\n 其模拟输入范围可在0 V至VREF（或2 × VREF）之间进行选择，可采用标准二进制或二进制补码输出编码。AD7265拥有2.5 V的片内参考电压，需用外部参考电压时，可超过此值，外部参考范围为100 mV至VDD。AD7265提供32引脚LFCSP和32引脚TQFP两种封装。\n\n 产品聚焦\n\n 具备两个完整的ADC功能，可实现两个通道同时采样和转换。通过编程，每个ADC均可设置为三路全/伪差分对或六路单端输入。两个通道的转换结果可通过独立的数据线同时获得，如果只有一个串行端口可用，则转换结果可通过一条数据线先后获得。 高呑吐量、低功耗。AD7265拥有1 MSPS的呑吐量，工作电压为3 V时，最大功耗仅有9 mW。 AD7265同时提供标准0 V至VREF输入范围和2 × VREF输入范围。 无流水线延迟。该器件采用两个标准逐次逼近型ADC，通过CS输入和一次性转换控制可实现对采样时间的精确控制。
