TLV5625CDR集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

TLV5625CDR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TLV5625CDR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)動器，以顯示單色或彩色圖像。

description

The TLV5625 is a dual 8-bit voltage output DAC

with a flexible 3-wire serial interface. The serial

interface is compatible with TMS320, SPI?,

QSPI?, and Microwire? serial ports. It is programmed

with a 16-bit serial string containing 4

control and 8 data bits.

The resistor string output voltage is buffered by an x2 gain rail-to-rail output buffer. The buffer features a

Class-AB output stage to improve stability and reduce settling time. The programmable settling time of the DAC

allows the designer to optimize speed versus power dissipation.

Implemented with a CMOS process, the device is designed for single supply operation from 2.7 V to 5.5 V. It

is available in an 8-pin SOIC package in standard commercial and industrial temperature ranges.
