AD9154BCPAZRL集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD9154BCPAZRL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AD9154BCPAZRL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 AD9154 is a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum sample rate of 2.4 GSPS, permitting multicarrier generation up to the Nyquist frequency in baseband mode. The AD9154 includes features optimized for direct conversion transmit applications, including complex digital modulation, input signal power detection, and gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with the ADRF6720-27 radio frequency quadrature modulator (AQM) from Analog Devices, Inc. In mix mode, the AD9154 DAC can reconstruct carriers in the second and third Nyquist zones. A serial port interface (SPI) provides the programming/readback of internal parameters.

The full-scale output current can be programmed over a range of 4 mA to 20 mA. The AD9154 is available in two different 88-lead LFCSP packages.
