DAC7614E屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由美國(guó)德州儀器公司制造生產(chǎn)的DAC7614E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。

DESCRIPTION

The DAC7614 is a quad, serial input, 12-bit, voltage

output digital-to-analog converter (DAC) with guaranteed

12-bit monotonic performance over the –40°C

to +85°C temperature range. An asynchronous reset

clears all registers to either mid-scale (800H) or zeroscale

(000H), selectable via the RESETSEL pin. The

device can be powered from a single +5V supply or

from dual +5V and –5V supplies.

Low power and small size makes the DAC7614 ideal

for process control, data acquisition systems, and

closed-loop servo-control. The device is available in

16-pin plastic DIP, 16-lead SOIC, or 20-lead SSOP

packages, and is guaranteed over the –40°C to +85°C

temperature range.
