AD7824BQ集成電路（IC）的模數(shù)轉換器（ADC）規(guī)格書PDF中文資料

AD7824BQ屬于集成電路（IC）的模數(shù)轉換器（ADC）。由亞德諾半導體技術有限公司制造生產的AD7824BQ模數(shù)轉換器（ADC）模數(shù)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(shù)字信號。一般來說，數(shù)字輸出是二進制補碼二進制數(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)轉換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉換器數(shù)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 AD7824 and AD7828 are high speed, multichannel, 8-bit ADCs with a choice of four (AD7824) or eight (AD7828) multiplexed analog inputs. A half-flash conversion technique gives a fast conversion rate of 2.5 μs per channel, and the parts have a built-in track-and-hold function capable of digitizing full-scale signals of 10 kHz (157 mV/μs slew rate) on all channels. The AD7824 and AD7828 operate from a single 5 V supply and have an analog input range of 0 V to 5 V, using an external 5 V reference.
