CS5581集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

CS5581屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由凌云邏輯制造生產(chǎn)的CS5581模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對模擬信號進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。

General Description

The CS5581 is a single-channel, 16-bit analog-to-digital converter capable of 200 kSps conversion rate. The input accepts a single-ended analog input signal. On-chip buffers provide high input impedance for both the AIN input and the VREF+ input. This significantly reduces the drive requirements of signal sources and reduces errors due to source impedances. The CS5581 is a delta-sigma converter capable of switching multiple input channels at a high rate with no loss in throughput. The ADC uses a low-latency digital filter architecture.
