AD5025BRUZ集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5025BRUZ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AD5025BRUZ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 AD5025/AD5045/AD5065 are low power, dual 12-/14-/16-bit buffered voltage output nanoDAC® DACs offering relative accuracy specifications of ±1 LSB INL with individual reference pins, and can operate from a single 4.5 V to 5.5 V supply. The AD5025/ AD5045/AD5065 also offer a differential accuracy specification of ±1 LSB. The parts use a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
