6通道、低噪聲、低功耗、24位Σ-Δ型ADC，內(nèi)置片內(nèi)儀表放大器和基準電壓源

AD7794/AD7795均為適合高精度測量應用的低功耗、低噪聲、完整模擬前端，內(nèi)置一個低噪聲24位/16位Σ-Δ型ADC，其中含有6個差分輸入，還集成了片內(nèi)低噪聲儀表放大器，因而可直接輸入小信號。\n\n 每款器件均內(nèi)置一個精密低噪聲、低漂移內(nèi)部帶隙基準電壓源，也可采用最多兩個外部差分基準電壓。其它片內(nèi)特性包括可編程激勵電流源、熔斷電流控制和偏置電壓產(chǎn)生器，利用偏置電壓產(chǎn)生器可將某一通道的共模電壓設置為AVDD/2。低端電源開關可用來在兩次轉(zhuǎn)換之間關斷橋式傳感器，從而使系統(tǒng)功耗降至較低。AD7794/AD7795可以采用內(nèi)部時鐘或外部時鐘工作，輸出數(shù)據(jù)速率可在4.17 Hz至470 ? 最高23位有效分辨率\n\n? 均方根（RMS）噪聲：40 nV（4.17 Hz時），85 nV（16.7 Hz時）\n\n? 功耗：400 μA（典型值）\n\n? 省電模式：最大1 μA\n\n? 低噪聲可編程增益儀表放大器;
