AD795集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）規(guī)格書PDF中文資料

AD795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AD795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 AD795 is a low noise, precision, FET input operational amplifier. It offers both the low voltage noise and low offset drift of a bipolar input op amp and the very low bias current of a FET input device. The 1014 Ω common-mode impedance insures that input bias current is essentially independent of common mode voltage and supply voltage variations.

The AD795 has both excellent dc performance and a guaranteed and tested maximum input voltage noise. It features 2 pA maximum input bias current and 500 μV maximum offset voltage, along with low supply current of 1.5 mA maximum.

Furthermore, the AD795 features a guaranteed low input noise of 3.3 μV p-p (0.1 Hz to 10 Hz) and a 11 nV/√Hz maximum noise level at 10 kHz. The AD795 has a fully specified and tested input offset voltage drift of only 10 μV/°C maximum. The AD795 is useful for many high input impedance, low noise applications. The AD795 is rated over the commercial temperature range of 0°C to +70°C.

The AD795 is available in an 8-lead SOIC package.
