MAX148

+2.7V至+5.25V、低功耗、8通道、串行10位ADC; ? 8通道單端或4通道差分輸入\n\n? 單電源供電：+2.7V至+5.25V\n\n? 內(nèi)部2.5V基準(zhǔn)電壓源(MAX149)\n\n? 低功耗：\n? 1.2mA（133ksps，3V電源）\n\n? 54μA（1ksps，3V電源）\n\n? 1μA（關(guān)斷模式）\n\n\n\n\n? SPI/QSPI/MICROWIRE/TMS320兼容型4線串行接口\n\n? 軟件可配置的單極性或雙極性輸入\n\n? 20引腳PDIP/SSOP封裝;

MAX148/MAX149 10位數(shù)據(jù)采集系統(tǒng)集成了8通道多路復(fù)用器、高帶寬采樣/保持功能和串行接口，提供高轉(zhuǎn)換速度和低功耗。它們采用+2.7V至+5.25V單電源供電，采樣速率為133ksps。兩款器件的模擬輸入均可通過軟件配置為單極性/雙極性和單端/差分工作模式。\n\n 4線串行接口直接連接到SPI/QSPI?和MICROWIRE?器件，無需外部邏輯。串行選通輸出支持直接連接到TMS320系列數(shù)字信號(hào)處理器。MAX148/MAX149使用內(nèi)部時(shí)鐘或外部串行接口時(shí)鐘進(jìn)行逐次逼近模數(shù)轉(zhuǎn)換。\n\n MAX149具有2.5V內(nèi)部基準(zhǔn)電壓源，而MAX148需要外部基準(zhǔn)電壓源。兩款器件都有一個(gè)電壓調(diào)整范圍為±1.5%的基準(zhǔn)電壓緩沖放大器。\n\n 這些器件提供一個(gè)硬連線的低電平有效SHDN引腳和軟件可選的關(guān)斷功能，并且可以編程為在轉(zhuǎn)換結(jié)束時(shí)自動(dòng)關(guān)斷。訪問串行接口即會(huì)自動(dòng)使MAX148/MAX149上電，而由于開啟時(shí)間快，可以在每次轉(zhuǎn)換之間將其關(guān)斷。該技術(shù)可以在采樣速率降低的情況下將電源電流降至60μA以下。\n\n MAX148/MAX149采用20引腳PDIP和20引腳SSOP封裝。\n\n 關(guān)于這些器件的4通道版本，請(qǐng)參見MAX1248/MAX1249數(shù)據(jù)手冊(cè)。\n\n ?\n\n
