128通道數(shù)字X射線模擬前端

AD8488是一款128通道模擬前端，為高性能數(shù)字X射線系統(tǒng)而設計。它的模擬通道由一個積分器和增益可選的單端轉(zhuǎn)低阻抗差分輸出組成。該模擬通道將X射線或光電二極管檢波器收集的電荷轉(zhuǎn)換成電壓信號。通道由CMOS晶體管組成，這些晶體管采用典型高輸入阻抗的CMOS門。該設備的積分器采用一系列可選電容值，產(chǎn)生與電荷有關(guān)的電壓，可適應廣泛的輸入電荷值。單端輸入轉(zhuǎn)差分輸出電壓放大器位于積分器之后，在這里偏移和低頻噪聲電壓從輸入電壓中減去。一條128:1通道差分MUX位于緩沖器之后，驅(qū)動模擬輸出緩沖。同時還提供開關(guān)驅(qū)動器和某些數(shù)字計時功能；這些功能全部集成在255引腳BGA基板上。全部128通道的電荷轉(zhuǎn)換是同 ? 128個積分通道 \n\n? 相關(guān)雙采樣糾錯 (CDS)\n- 校正VOS和LF噪聲\n\n? 功耗/通道\n- 正常值：11 mW\n- 低功耗：4 mW\n\n? 低輸入漏電流\n- 1.5 pA（典型值）\n\n? 低折合到輸入端噪聲 (QNI)\n- 1000 e?rms（典型值）\n\n? 線性誤差\n- 0.03%（典型值）\n\n? 緊湊型17 mm x 17 mm BGA封裝 \n\n? 濾波器時間常數(shù)可選 \n\n? 4種可選輸入電荷范圍 \n\n? 10種可選增益范圍;
