AD5342BRUZ集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5342BRUZ属于集成电路（IC）的数模转换器（DAC）。由亚德诺半导体技术有限公司制造生产的AD5342BRUZ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。

GENERAL DESCRIPTION

The AD5332/AD5333/AD5342/AD5343 are dual 8-, 10-, and 12-bit DACs. They operate from a 2.5 V to 5.5 V supply consuming just 230 µA at 3 V, and feature a power-down pin, PD that further reduces the current to 80 nA. These devices incorporate an on-chip output buffer that can drive the output to both supply rails, while the AD5333 and AD5342 allow a choice of buffered or unbuffered reference input.
