AD9057集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書(shū)PDF中文資料

AD9057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AD9057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(lèi)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。

PRODUCT DESCRIPTION

The AD9057 is an 8-bit monolithic analog-to-digital converter optimized for low cost, low power, small size, and ease of use. With 40 MSPS, 60 MSPS, or 80 MSPS encode rate capability and full-power analog bandwidth of 120 MHz, the component is ideal for applications requiring excellent dynamic performance. To minimize system cost and power dissipation, the AD9057 includes an internal 2.5 V reference and a track-and-hold (T/H) circuit. The user must provide only a 5 V power supply and an encode clock. No external reference or driver components are required for many applications.
