10位、8通道、350 kSPS、串行ADC

AD7811和AD7812均为高速、低功耗、10位模数转换器（ADC），采用2.7 V至5.5 V单电源供电。这些器件内置一个2.3 微秒（µs）逐次逼近型模数转换器、一个片内采样保持放大器、一个2.5 V片内基准电压源和一个高速串行接口，该串行接口与大多数数字信号处理器（DSP）和微控制器的串行接口兼容。用户也可选择采用外部基准电压，将它与VREF引脚相连，并在控制寄存器中设置EXTREF位。VREF引脚可与VDD引脚相连。吞吐量较低时，可以利用省电模式在转换之间自动关断。\n\n 利用AD7811和AD7812的控制寄存器，可以将输入通道配置为单端或伪差分输入。该控制寄存器还具有 • 10位ADC，转换时间为2.3微秒\n\n• AD7812拥有8个单端输入，可配置为相对于1个共用输入的7个伪差分输入，或配置为4个独立伪差分通道\n\n• 片上采样保持\n\n• 片上基准电压源：2.5 V ± 2.5%\n\n• 工作电压范围：2.7 V至5.5 V\n\n• 额定电压范围：2.7 V至3.6 V及5 V±10%;
