雙通道、差分、16位、1 MSPS PulSAR 12.0 mW ADC，采用QSOP封裝

AD7903是一款雙通道16位、逐次逼近型模數(shù)轉(zhuǎn)換器(ADC)，各ADC采用單電源(VDDx)供電。它內(nèi)置兩個(gè)低功耗、高速、16位采樣ADC和一個(gè)多功能串行接口端口。在CNVx上升沿，AD7903對(duì)INx+與INx-引腳之間的電壓差進(jìn)行采樣，這兩個(gè)引腳上的電壓擺幅通常在0 V至 VREF之間、相位相反。REFx引腳的基準(zhǔn)電壓(VREF)由外部提供，可獨(dú)立于電源電壓引腳(VDDx)來(lái)設(shè)定。該器件的功耗與吞吐速率呈線性變化關(guān)系。\n\n SPI兼容串行接口還能利用SDIx輸入將幾個(gè)ADC以菊花鏈形式連結(jié)到單個(gè)三線式總線上，并提供一個(gè)可選的繁忙指示。采用獨(dú)立電源VIOx時(shí)，它與1.8V、2 ? 16位分辨率、無(wú)失碼\n\n? 吞吐速率： 1 MSPS\n\n? 低功耗： \n7.0 mW（1 MSPS，僅VDD1 和VDD2） \n12.0 mW（1 MSPS，總功耗）\n140 μW (10 kSPS) \n\n? 積分非線性(INL)： 典型值：±0.5 LSB；最大值：±2.0 LSB \n\n? 真差分模擬輸入范圍： ±VREF\n0 V至VREF（VREF 在 2.4 V 至5.1 V之間）\n可使用任一輸入范圍\n可采用ADA4941-1輕松驅(qū)動(dòng)\n\n? 信納比(SINAD)： 93.5 dB (1 kHz);
