AD3541R集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

AD3541R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AD3541R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。

GENERAL DESCRIPTION

The AD3541R is a low drift, single channel, ultra-fast, 16-bit accuracy,

voltage output digital-to-analog converter (DAC) that can be

configured in multiple voltage span ranges. The AD3541R operates

with a fixed 2.5 V reference.

The device incorporates three drift compensating feedback resistors

for the internal transimpedance amplifier (TIA) that scales the

output voltage. The AD3541R has five preconfigured output ranges:

0 V to 2.5 V, 0 V to 5 V, 0 V to 10 V, ?5 V to +5 V, and ?2.5 V to

+7.5 V.

The DAC can operate in fast mode for maximum speed or precision

mode for maximum accuracy.

The serial peripheral interface (SPI) can be configured in single SPI

(classic SPI) mode or dual SPI mode with single date rate (SDR) or

double data rate (DDR), with logical levels from 1.2 V to 1.8 V.

To improve device robustness, cyclic redundancy check (CRC) can

be enabled. Multiple error checkers have also been integrated to

detect VREF failures or memory map corruption.

The AD3541R is specified over the extended industrial temperature

range (–40°C to +105°C).
