ADV7127屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADV7127數(shù)模轉(zhuǎn)換器（DAC）數(shù)模轉(zhuǎn)換器（DAC、D/A、D2A 或 D 轉(zhuǎn) A）可將數(shù)字信號(hào)轉(zhuǎn)換為緩沖或無(wú)緩沖的模擬電壓或電流。DAC 架構(gòu)是否適合特定應(yīng)用，要取決于分辨率和采樣頻率。DAC 通常用于音樂播放器，將數(shù)字?jǐn)?shù)據(jù)流轉(zhuǎn)換為模擬音頻流。它們還用于電視和手機(jī)，將數(shù)字視頻數(shù)據(jù)轉(zhuǎn)換為模擬視頻信號(hào)，再連接到屏幕驅(qū)動(dòng)器，以顯示單色或彩色圖像。

GENERAL DESCRIPTION

The ADV7127 (ADV?) is a high speed, digital-to-analog convertor on a single monolithic chip. It consists of a 10-bit, video D/A converter with on-board voltage reference, comple mentary outputs, a standard TTL input interface and high impedance analog output current sources.

The ADV7127 has a 10-bit wide input port. A single +5 V/+3.3 V power supply and clock are all that are required to make the part functional.

The ADV7127 is fabricated in a CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. The ADV7127 is available in a small outline 28-lead SOIC or 24-lead TSSOP package.

The ADV7127 TSSOP package also has a power-down mode. Both ADV7127 packages have a power standby mode. The ADV7127 TSSOP package has an on-board voltage reference circuit. The ADV7127 SOIC package requires an external reference.
