DAC7612屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由美國德州儀器公司制造生產(chǎn)的DAC7612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)字信號轉(zhuǎn)換為緩沖或無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，將數(shù)字視頻數(shù)據(jù)轉(zhuǎn)換為模擬視頻信號，再連接到屏幕驅(qū)動器，以顯示單色或彩色圖像。

DESCRIPTION

The DAC7612 is a dual, 12-bit digital-to-analog converter

(DAC) with guaranteed 12-bit monotonicity

performance over the industrial temperature range. It

requires a single +5V supply and contains an input

shift register, latch, 2.435V reference, a dual DAC, and

high speed rail-to-rail output amplifiers. For a fullscale

step, each output will settle to 1 LSB within 7ms

while only consuming 3.7mW.

The synchronous serial interface is compatible with a

wide variety of DSPs and microcontrollers. Clock

(CLK), Serial Data In (SDI), Chip Select (CS) and

Load DACs (LOADDACS) comprise the serial interface.

The DAC7612 is available in an 8-lead SOIC package

and is fully specified over the industrial temperature

range of –40°C to +85°C.
