AD8300AN集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）規(guī)格書PDF中文資料

AD8300AN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AD8300AN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)字數(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。

GENERAL DESCRIPTION

The AD8300 is a complete 12-bit, voltage-output digital-to analog converter designed to operate from a single +3 volt supply. Built using a CBCMOS process, this monolithic DAC offers the user low cost, and ease-of-use in single-supply +3 volt systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V making this device ideal for battery operated applications.

The 2.0475 V full-scale voltage output is laser trimmed to maintain accuracy over the operating temperature range of the device. The binary input data format provides an easy-to-use one-half-millivolt-per-bit software programmability. The voltage outputs are capable of sourcing 5 mA.

A double buffered serial data interface offers high speed, three wire, DSP and microcontroller compatible inputs using data in (SDI), clock (CLK) and load strobe (LD) pins. A chip select (CS) pin simplifies connection of multiple DAC packages by enabling the clock input when active low. Additionally, a CLR input sets the output to zero scale at power on or upon user demand.

The AD8300 is specified over the extended industrial (–40°C to +85°C) temperature range. AD8300s are available in plastic DIP, and low profile 1.5 mm height SO-8 surface mount packages.
