AD13280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AD13280模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對(duì)模擬信號(hào)進(jìn)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(hào)。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)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(jìn)行選擇。

GENERAL DESCRIPTION

The AD13280 is a complete, dual-channel, signal processing solution that includes on-board amplifiers, references, ADCs, and output termination components to provide optimized system performance. The AD13280 has on-chip track-and-hold circuitry and uses an innovative multipass architecture to achieve 12-bit, 80 MSPS performance. The AD13280 uses innovative high density circuit design and laser-trimmed thin-film resistor networks to achieve exceptional channel matching, impedance control, and performance while maintaining excellent isolation and providing for significant board area savings.
