12位、2.7 V至5.25 V、1.5 MSPS低功耗ADC

AD7470/AD7472分别是10位/12位高速、低功耗逐次逼近型ADC，工作电压为2.7 V至5.25 V单电源，12位AD7472的最高呑吐量可达1.5 MSPS，10位AD7470则可达1.75 MSPS。该器件内置一个低噪声、宽带宽采样/保持放大器，可处理20 MHz以上的输入频率。\n\n 转换过程和数据采集过程均通过标准控制输入进行控制，可与微处理器或DSP轻松连接。输入信号在 CONVST的下降沿进行采样，而转换同时在此处启动。转换开始时，BUSY电平升高，在 CONVST下降沿531.66 ns之后降低（AD7472的时钟频率为26 MHz），表示转换完成。该器件无 • 额定电压(VDD)：2.7 V至5.25 V\n\n• 1.5 MSPS（12位）\n\n• 低功耗：\n典型3.54 mW（1.2 MSPS，3 V电源）\n典型8.7 mW（1.5 MSPS，5 V电源）\n\n• 灵活的功耗/呑吐量管理\n\n\n\n• 宽输入带宽：70 dB\n（500 kHz输入频率）\n\n• 无流水线延迟\n\n• 高速并行接口\n\n• 休眠模式：50 nA（典型值）\n\n• 24引脚SOIC和TSSOP封装;
