AD9430屬于集成電路（IC）的模數轉換器（ADC）。由亞德諾半導體技術有限公司制造生產的AD9430模數轉換器（ADC）模數轉換器（ADC、A/D 或 A 轉 D）對模擬信號進行采樣，例如由麥克風采集的聲音或傳感器的輸出，然后將其轉換為數字信號。一般來說，數字輸出是二進制補碼二進制數，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數轉換器可按照位數、采樣率、輸入數、接口、轉換器數和架構（例如自適應增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進行選擇。

GENERAL DESCRIPTION

The AD9430 is a 12-bit, monolithic, sampling analog-to-digital converter (ADC) optimized for high performance, low power, and ease of use. The product operates up to a 210 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) and reference, are included on the chip to provide a complete conversion solution.
