描述 Description

Maxim's MX7228 contains eight 8-bit voltage output digital-to-analog converters (DACs) with separate input latches and output buffers for simple microprocessor and TTL/CMOS interfacing. The MX7228 maintains 8-bit accuracy over the full operating temperature range without external trimming. Internally, data transfer into the data registers is via a common 8-bit TTL/CMOS compatible input bus. Logic inputs A2, A1, and A0 control which DAC is loaded after active-low WR goes low.

簡(jiǎn)介

MX7228屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由制造生產(chǎn)的MX7228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(wú)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(lè)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。
