AD9235集成電路（IC）的模數轉換器（ADC）規(guī)格書PDF中文資料

AD9235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AD9235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 AD9235 is a family of monolithic, single 3 V supply, 12-bit, 20/40/65 MSPS analog-to-digital converters (ADCs). This family features a high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9235 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 20/40/65 MSPS data rates and guarantee no missing codes over the full operating temperature range.
