MCP4728中文资料12-Bit Quad Output DAC w/EEPROM and I2C™数据手册Microchip规格书

描述 Description

MCP4728 is a quad channel, 12-bit voltage output Digital-to-Analog Converter with non-volatile memory and I2C compatible Serial Interface. The user can program the DAC input codes, device configuration bits, and I2C address bits to the non-volatile memory (EEPROM) by using I2C™Compatible interface commands. The non-volatile memory feature enables the DAC device to hold the DAC input codes during power-off time, allowing the DAC outputs to be available immediately after power-up.

简介

MCP4728属于集成电路（IC）的数模转换器（DAC）。由制造生产的MCP4728数模转换器（DAC）数模转换器（DAC、D/A、D2A 或 D 转 A）可将数字信号转换为缓冲或无缓冲的模拟电压或电流。DAC 架构是否适合特定应用，要取决于分辨率和采样频率。DAC 通常用于音乐播放器，将数字数据流转换为模拟音频流。它们还用于电视和手机，将数字视频数据转换为模拟视频信号，再连接到屏幕驱动器，以显示单色或彩色图像。
