DAC63002集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

DAC63002屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由德州儀器制造生產(chǎn)的DAC63002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(jī)，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(dòng)器，以顯示單色或彩色圖像。

3 Description

The 12-bit DAC63001 and DAC63002, and the 10?bit

DAC53001 and DAC53002 (collectively referred to as

the DACx300x) are a pin-compatible family of ultralow-

power, single-channel and dual-channel, buffered

voltage-output and current-output smart digital-toanalog

converters (DACs). The DACx300x devices

support Hi-Z power-down mode and Hi-Z output

during power-off conditions. The DAC outputs provide

a force-sense option for use as a programmable

comparator and current sink. The multifunction GPIO,

function generation, and NVM enable these smart

DACs for processor-less applications and design

reuse. These devices automatically detect I2C,

PMBus, and SPI interfaces and contain an internal

reference.

The feature set combined with the tiny package and

ultra-low power make these smart DACs an excellent

choice for applications such as land mobile radios,

pulse oximeters, notebook PCs, and other batteryoperated

applications for biasing, calibration, and

waveform generation.
