AD876是一款CMOS、160 mW、10位、20 MSPS模数转换器(ADC)，内置一个片内输入采样保持放大器。它采用多级流水线架构，内置输出纠错逻辑，可提供精确的性能，并保证在整个工作温度范围内无失码。参考输入的驱动和检测连接将外部压降降至最低。可以将AD876置于待机工作模式，此时功耗降至50 mW以下。数字I/O接口支持+5 V或+3.3 V逻辑。可以将数字输出引脚置于高阻态；输出格式为标准二进制编码。AD876的速度、分辨率和单电源工作方式非常适合视频、多媒体、成像、高速数据采集和通信等各种应用。其低功耗和单电源工作方式符合高速便携式应用的要求。其速度和分辨率特性则特别适合电荷耦合器件(CCD)输入系统，如彩色扫描仪、数码复印机、数码相机和便携式数码摄录机等。AD876提供节省空间的28引脚SOIC和48引脚薄型四方扁平(TQFP)两种封装，额定温度范围为0°C至+70°C商用温度范围。
The AD876 is a CMOS, 160 mW, 10-bit, 20 MSPS analog-to-digital converter (ADC). The AD876 has an on-chip input sample-and-hold amplifier. By implementing a multistage pipelined architecture with output error correction logic, the AD876 offers accurate performance and guarantees no missing codes over the full operating temperature range. Force and sense connections to the reference inputs minimize external voltage drops.The AD876 can be placed into a stand-by mode of operation reducing the power below 50 mW. The AD876’s digital I/O interfaces to either +5 V or +3.3 V logic. Digital output pins can be placed in a high impedance state; the format of the output is straight binary coding.The AD876's speed, resolution and single-supply operation ideally suit a variety of applications in video, multimedia, imaging, high speed data acquisition and communications. The AD876's low power and single-supply operation satisfy requirements for high speed portable applications. Its speed and resolution ideally suit charge coupled device (CCD) input systems such as color scanners, digital copiers, electronic still cameras and camcorders.The AD876 comes in a space saving 28-pin SOIC and 48-pin thin quad flatpack (TQFP) and is specified over the commercial (0°C to +70°C) temperature range.
