描述 Description

MCP48CMB24 is a quad channel, 12-bit, buffered voltage output Digital-to-Analog Converter (DAC) with MTP memory and an SPI Compatible Serial Interface. This?device provides four different voltage reference options: device VDD, external VREF (Buffered or unbuffered) and internal bandgap. It offers 1 LSB Integral Non-Linearity (INL) with low power consumption and fast settling time of 4μs. This device has integrated MTP memory that can be written up to 32 times, for reach specific register. It is suitable for consumer and industrial applications, such as set point or offset trimming, sensor calibrations and motor control applications. For different resolutions and number of output channels, please check out our other parts in the MCP48CMBxx family.

簡(jiǎn)介

MCP48CMB24屬于集成電路（IC）的數(shù)模轉(zhuǎn)換器（DAC）。由制造生產(chǎn)的MCP48CMB24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。
