AD5311BRT集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5311BRT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AD5311BRT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 AD5301/AD5311/AD5321 are single 8-bit, 10-bit, and 12-bit buffered voltage-output DACs that operate from a single 2.5 V to 5.5 V supply, consuming 120 µA at 3 V. The on-chip output amplifier allows rail-to-rail output swing with a slew rate of 0.7 V/µs. It uses a 2-wire (I2C compatible) serial interface that operates at clock rates up to 400 kHz. Multiple devices can share the same bus.
