AD7763集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD7763屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD7763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 AD7763 high performance, 24-bit, Σ-Δ analog-to-digital converter (ADC) combines wide input bandwidth and high speed with the benefits of Σ-Δ conversion, as well as performance of 107 dB SNR at 625 kSPS, making it ideal for high speed data acquisition. A wide dynamic range, combined with significantly reduced antialiasing requirements, simplifies the design process.
