MCP47DA1中文资料6-Bit Single Output DAC w/Command Code I2C™数据手册Microchip规格书

描述 Description

MCP47DA1 is a volatile, 6-Bit digital Digital-to-Analog Converter (DAC) with a windowed output for server voltage margining applications. The MCP47DA1 has a windowed output (1/3 to 2/3 of VREF). The DAC setting is controlled through an I2C™Compatible serial interface. The I2C™Compatible slave addresses of “010 1110” and “011 1110” are supported.

简介

MCP47DA1属于集成电路（IC）的数字电位计。由制造生产的MCP47DA1数字电位计数字电位器是一系列集成电路器件，可提供类似于传统机械电位器或变阻器的可调节电阻，但通过电子信号而非机械输入来进行控制。虽然这些器件的电阻可耗散的电能相对有限，但其电子控制能力有助于小型化、自动化和远程控制信号级模拟电路，而这些电路本来可能会使用机械电位器。
