10位、2.7 V至5.25 V、1.75 MSPS低功耗ADC

AD7470/AD7472分別是10位/12位高速、低功耗逐次逼近型ADC，工作電壓為2.7 V至5.25 V單電源，12位AD7472的最高呑吐量可達(dá)1.5 MSPS，10位AD7470則可達(dá)1.75 MSPS。該器件內(nèi)置一個低噪聲、寬帶寬采樣/保持放大器，可處理20 MHz以上的輸入頻率。 轉(zhuǎn)換過程和數(shù)據(jù)采集過程均通過標(biāo)準(zhǔn)控制輸入進(jìn)行控制，可與微處理器或DSP輕松連接。輸入信號在CONVST的下降沿進(jìn)行采樣，而轉(zhuǎn)換同時在此處啟動。轉(zhuǎn)換開始時，BUSY電平升高，在CONVST下降沿531.66 ns之后降低（AD7472的時鐘頻率為26 MHz），表示轉(zhuǎn)換完成。該器件不存在流水線延 ? 額定電壓(VDD)：2.7 V至5.25 V\n\n? 1.75 MSPS（10位）\n\n? 低功耗\n典型3.34 mW（1.5 MSPS，3 V電源\n典型7.97 mW（1.75 MSPS，5 V電源）\n\n? 靈活的功耗/呑吐量管理\n\n\n\n? 寬輸入帶寬：\n70 d典型信噪比B（500 kHz輸入頻率）\n\n? 無流水線延遲\n\n? 高速并行接口\n\n? 休眠模式：50 nA（典型值）\n\n? 24引腳SOIC和TSSOP封裝;
