低功耗、雙通道、24位Σ-Δ型ADC

AD7787是一款適合低頻測(cè)量應(yīng)用的低功耗、完整模擬前端，內(nèi)置一個(gè)低噪聲24位Σ-Δ型ADC，該ADC具有一個(gè)差分輸入和一個(gè)可緩沖或無(wú)緩沖的單端輸入。\n\n 該器件采用內(nèi)部時(shí)鐘工作，因此，用戶不必為其提供時(shí)鐘源。AD7787的輸出數(shù)據(jù)速率可通過(guò)軟件編程設(shè)置，可在9.5 Hz至120 Hz的范圍內(nèi)變化，更新速率較低時(shí)均方根（RMS）噪聲為1.1 μV。內(nèi)部時(shí)鐘頻率可以使用系數(shù)2、4或8進(jìn)行分頻，從而可以降低功耗。更新速率、截止頻率和建立時(shí)間與時(shí)鐘頻率成比例變化。\n\n 該器件采用2.5 V至5.25 V電源供電。工作電壓為3 V時(shí)，最大功耗為225 μW，采用10引腳MS ? 電源：\n- 工作電壓：2.5 V至5.25 V\n- 正常模式：最大75 μA\n- 省電模式：最大1 μA\n\n? 均方根（RMS）噪聲：1.1 μV（9.5 Hz更新速率時(shí)）\n\n? 19.5位峰－峰值分辨率（22位有效分辨率）\n\n? 積分非線性：3.5 ppm（典型值）\n\n? 50 Hz和60 Hz同時(shí)抑制;
