20位、引腳可編程的超低功耗Σ?Δ型ADC

AD7781是一款完整的低功耗前端解決方案，適用于橋式傳感器產(chǎn)品，包括電子秤、應(yīng)變計(jì)和壓力傳感器。它內(nèi)置一個(gè)精密、低功耗、20位Σ-Δ型ADC，一個(gè)片內(nèi)低噪聲可編程增益放大器(PGA)，以及一個(gè)片內(nèi)振蕩器。\n\n AD7781功耗僅為330 μA，因此特別適合要求極低功耗的便攜式或電池供電產(chǎn)品。該器件還提供省電模式，不執(zhí)行轉(zhuǎn)換時(shí)，用戶可以切斷對(duì)橋式傳感器的供電，并使該器件進(jìn)入省電模式，從而延長產(chǎn)品的電池使用時(shí)間。\n\n 為便于使用，AD7781的所有特性均由專用引腳控制。每次發(fā)生數(shù)據(jù)讀取操作時(shí)，8個(gè)狀態(tài)位便會(huì)附加到20位轉(zhuǎn)換結(jié)果上。這些狀態(tài)位含有一個(gè)碼序列，可用來確認(rèn)串 ? 引腳可編程的濾波器響應(yīng)\n更新速率：10 Hz或16.7 Hz \n\n? 引腳可編程的儀表放大器增益\n\n? 引腳可編程省電和復(fù)位功能 \n\n? 狀態(tài)功能 \n\n\n\n? 內(nèi)部時(shí)鐘振蕩器\n\n? 內(nèi)部電橋關(guān)斷開關(guān) \n\n? 電流:\n115 μA（典型值，G = 1）\n330 μA（典型值，G = 128）\n\n? 50 Hz/60 Hz同時(shí)抑制 \n\n? 欲了解更多特性，請(qǐng)參考數(shù)據(jù)手冊(cè);
