AD7641規(guī)格書詳情

AD7641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AD7641模數(shù)轉(zhuǎn)換器(ADC)模數(shù)轉(zhuǎn)換器(ADC、A/D 或 A 轉(zhuǎn) D)對模擬信號進行采樣,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。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(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)進行選擇。

GENERAL DESCRIPTION

The AD8475 is a fully differential, attenuating amplifier with integrated precision gain resistors. It provides precision attenuation (by 0.4 or 0.8), common-mode level shifting, and single-ended-to-differential conversion along with input overvoltage protection. Power dissipation on a single 5 V supply is only 16 mW.

The AD8475 is a simple to use, fully integrated precision gain block, designed to process signal levels of up to ±10 V on a single supply. It provides a complete interface to make industrial level signals directly compatible with the differential input ranges of low voltage high performance 16-bit or 18-bit single-supply successive approximation (SAR) analog-to-digital converters (ADCs).

The AD8475 comes with two standard pin-selectable gain options: 0.4 and 0.8. The gain of the part is set by driving the input pin corresponding to the appropriate gain.

The AD8475 also provides overvoltage protection from large industrial input voltages up to ±15 V while operating on a single 5 V supply. The VOCM pin adjusts the output voltage common mode for precision level shifting, to match the ADC’s input range and maximize dynamic range.
