3HXH1000-385提及智能化或工業(yè)自動(dòng)化，我們的第一反應(yīng)往往是APP很強(qiáng)大、人機(jī)界面很炫或是主控芯片性能很高……但是，在這些看得到、感受得到的技術(shù)背后，模擬技術(shù)的作用其實(shí)是巨大的，它像一個(gè)低調(diào)的巨人，默默地支撐著智能化、自動(dòng)化這些光鮮的技術(shù)應(yīng)用從無(wú)到有、從基礎(chǔ)到強(qiáng)大。
3HXH1000-385在可預(yù)見(jiàn)的未來(lái)，智能化也好，工業(yè)4.0也好，都對(duì)模擬技術(shù)提出了更高的需求。首先是高精度，為了保證工廠自動(dòng)化以及控制自動(dòng)化的質(zhì)量及人身安全，對(duì)于模擬芯片的精度要求未來(lái)將會(huì)繼續(xù)提升。其次是高速采集需求，在向全自動(dòng)化的發(fā)展過(guò)程中，工廠需要十倍甚至百倍的數(shù)據(jù)點(diǎn)，因此對(duì)信號(hào)的高速和實(shí)時(shí)采集也是必不可少的要求，對(duì)模擬芯片特別模擬信號(hào)輸入芯片的精度提出了更高的要求。此外，小型化是未來(lái)的必然趨勢(shì)，因此也要求芯片持續(xù)向小型化、集成化的方向發(fā)展。
24位遭遇瓶頸，32位Δ-Σ ADC應(yīng)時(shí)而生
3HXH1000-385 那么，在目前的模擬數(shù)據(jù)采集芯片和解決方案方面，有哪些已經(jīng)出現(xiàn)或者將要面臨的技術(shù)挑戰(zhàn)呢？
德州儀器 (TI) 半導(dǎo)體事業(yè)部中國(guó)區(qū)模擬業(yè)務(wù)拓展經(jīng)理朱文斌介紹，目前24位ADC(模數(shù)變換器)在工業(yè)應(yīng)用已經(jīng)遇到瓶頸。以可編程邏輯控制器 (PLC)系統(tǒng)為例，其中的ADC位數(shù)從10位-20位不等，24位已經(jīng)是最高的位數(shù)了。但是對(duì)于石油勘探等對(duì)溫度控制要求很高的客戶來(lái)說(shuō)，他們?cè)谌珳囟确秶鷥?nèi)都要求更高的分辨率，24位往往不夠用。由于性價(jià)比比較高的芯片全是24位Δ-Σ ADC，因此許多客戶首先提出了更高精度的需求。此外，對(duì)于工業(yè)用高精度天平來(lái)說(shuō)，也需要高于24位ADC的應(yīng)用。24位的ADC市場(chǎng)已經(jīng)基本處于飽和狀態(tài)，亟需在本身的架構(gòu)、精度上尋求突破。而除了高精度，對(duì)于工業(yè)現(xiàn)場(chǎng)用的各種采集板卡、系統(tǒng)來(lái)說(shuō)，都要求溫度和系統(tǒng)長(zhǎng)時(shí)間工作的穩(wěn)定性，因此要求IC器件具有低溫漂漂移的特性。
3HXH1000-385順應(yīng)上述市場(chǎng)需求，TI在實(shí)時(shí)性、高速、高精度以及小型化等方向綜合考量，推出了ADS1262/1263兩款32位增量-累加模數(shù)轉(zhuǎn)換器（Δ-Σ ADC），這兩款器件將高分辨率、低噪聲和集成故障檢測(cè)組合在一起，成功解決了過(guò)去在器件評(píng)估和選型時(shí)，所需的性能和特性無(wú)法兼得的問(wèn)題。
ADS1262/1263在2.5SPS采樣率情況下，還能采到7nVRms均值信號(hào)的水平，這點(diǎn)對(duì)于輸入信號(hào)為10mV以下或者更小的電橋應(yīng)用是必不可少的。它們的偏移誤差漂移也比同類(lèi)解決方案低80%，從而確保了整個(gè)溫度范圍內(nèi)的測(cè)量穩(wěn)定性。38 kSPS的最大輸出數(shù)據(jù)速率使得它們特別適用于高數(shù)據(jù)吞吐量工業(yè)應(yīng)用中。
