CMOS 16-Bit, 468.75 kHz, Sigma-Delta ADC

GENERAL DESCRIPTION The AD7721 is a complete low power, 12-/16-bit, sigma-delta ADC. The part operates from a +5 V supply and accepts a differential input of 0 V to 2.5 V or ±1.25 V. The analog input is continuously sampled by an analog modulator at twice the clock frequency eliminating the need

CMOS、12或16位、312.5 kHz/468.75 kHz Σ-Δ 型ADC

AD7721是一款完全低功耗、12位或16位Σ-Δ型ADC，采用+5 V電源供電，接受0 V至2.5 V或±1.25 V差分輸入范圍。模擬輸入由模擬調(diào)制器以時鐘頻率兩倍的速度連續(xù)采樣，因而無需外部采樣保持電路。調(diào)制器輸出由兩個串聯(lián)的有限脈沖響應(yīng)（FIR）數(shù)字濾波器處理。在大多數(shù)情況下，通過片內(nèi)濾波可將外部抗混疊要求降至一階。當(dāng)主時鐘頻率等于15 MHz時，階躍輸入的建立時間為218.4 μs，而濾波器的群延遲為109.2 μs。\n\n AD7721的輸入帶寬最高可達(dá)229.2 kHz，相應(yīng)的輸出字速率為468.75 kHz。該器件也可采用較低的時鐘頻率工作。由于采樣速率、濾波器轉(zhuǎn)折 ? 16位Σ-Δ型ADC\n\n? 輸出字速率（OWR）：468.75 kHz\n\n? 無失碼\n\n? 低通數(shù)字濾波器\n\n? 高速串行接口;
