AD7812規(guī)格書詳情

AD7812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AD7812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 AD7811 and AD7812 are high speed, low power, 10-bit A/D converters that operate from a single 2.7 V to 5.5 V supply. The devices contain a 2.3 μs successive approximation A/D converter, an on-chip track/hold amplifier, a 2.5 V on-chip reference and a high speed serial interface that is compatible with the serial interfaces of most DSPs (Digital Signal Processors) and microcontrollers. The user also has the option of using an external reference by connecting it to the VREF pin and setting the EXTREF bit in the control register. The VREF pin may be tied to VDD. At slower throughput rates the power-down mode may be used to automatically power down between conversions.
