AD746集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD746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AD746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。

PRODUCT DESCRIPTION

The AD746 is a dual operational amplifier, consisting of two AD744 BiFET op amps on a single chip. These precision monolithic op amps offer excellent dc characteristics plus rapid settling times, high slew rates and ample bandwidths. In addition, the AD746 provides the close matching ac and dc characteristics inherent to amplifiers sharing the same monolithic die.

The single pole response of the AD746 provides fast settling: 500 ns to 0.01. This feature, combined with its high dc precision, makes it suitable for use as a buffer amplifier for 12- or 14-bit DACs and ADCs. Furthermore, the AD746’s low total harmonic distortion (THD) level of 0.0001 and very close matching ac characteristics make it an ideal amplifier for many demanding audio applications.
