高速、微处理器兼容型、CMOS、8位采样ADC

AD7821是一款高速、8位采样模数转换器（ADC），性能优于颇受欢迎的AD7820。该器件提供660 ns转换时间（AD7820为1.36 µs）及100 kHz信号带宽（AD7820为6.4 kHz）。采样点的界定更精确，在RD的WR下降沿上。该器件具有VSS引脚（引脚19），可采用±5 V电源供电，支持双极性输入信号。也可以采用单极性输入，此时VSS引脚可接地，并且AD7821与AD7820一样，采用+5 V单电源供电。\nAD7821内置采样保持功能，能够将最大100 kHz带宽的满量程信号数字化。它还采用半快速型（half-flash）转换技术，从而无需为ADC提供CLK信号。\nA 快速转换时间：660 ns（最大值）\n100 kHz采样保持功能\n采样率：1 MHz\n双极性和单极性输入范围\n比率基准电压输入\n无外部时钟\n可在扩展温度范围内工作\n超小型20引脚DIP、SOIC和表面贴装封装;
