MCP4725中文资料12-Bit Single Output DAC w/EEPROM and I2C™数据手册Microchip规格书

描述 Description

MCP4725 is a single channel, 12-bit, voltage output Digital-to-Analog Converter with integrated EEPROM and an I2C Compatible Serial Interface.The MCP4725 DAC offers integrated non-volatile memory (EEPROM) which allows DAC register and configuration bit values to be saved at power off. The VREF pin or device VDD can be selected as the DAC’s reference voltage. Power-Down modes enable system current reduction when the DAC output voltage is not required. These devices are available in small 6-pin SOT-23 and DFN 2x2 mm packages.

简介

MCP4725属于集成电路（IC）的数模转换器（DAC）。由制造生产的MCP4725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。
