AD7823YR集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD7823YR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AD7823YR模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)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(hào)。一般來(lái)說(shuō)，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 AD7823 is a high speed, low power, 8-bit A/D converter that operates from a single 2.7 V to 5.5 V supply. The part contains a 4 μs typ successive approximation A/D converter, inherent track-and-hold functionality (with a pseudo differential input) and a high speed serial interface that interfaces to most microcontrollers. The AD7823 is fully specified over a temperature range of –40°C to +125°C.
