AD5725集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

AD5725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AD5725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 AD5726 is a quad, 12-bit, serial input, voltage output digital-to-analog converter (DAC) fabricated on Analog Devices, Inc., iCMOS® process technology1 that offers guaranteed monotonicity and integral nonlinearity (INL) of ±1 LSB maximum.

Output voltage swing is set by two reference inputs, VREFP and VREFN. The DAC offers a unipolar positive output range when the VREFN input is set to 0 V and the VREFP input is set to a positive voltage. A similar configuration with VREFP at 0 V and VREFN at a negative voltage provides a unipolar negative output range.

Bipolar outputs are configured by connecting both VREFP and VREFN to nonzero voltages. This method of setting output voltage ranges has advantages over the bipolar offsetting methods because it is not dependent on internal and external resistors with different temperature coefficients.
