AD7478AARM集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD7478AARM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AD7478AARM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 AD7476A/AD7477A/AD7478A are 12-bit, 10-bit, and 8-bit high speed, low power, successive-approximation ADCs, respectively. The parts operate from a single 2.35 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. The parts contain a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 13 MHz.
