DAC7664YR集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC7664YR属于集成电路（IC）的数模转换器（DAC）。由美国德州仪器公司制造生产的DAC7664YR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。

DESCRIPTION

The DAC7664 is a 16-bit, quad voltage output

digital-to-analog converter (DAC) with 16-bit monotonic

performance over the specified temperature range. It

accepts 16-bit parallel input data, has double-buffered

DAC input logic (allowing simultaneous update of all

DACs), and provides a readback mode of the internal input

registers. Programmable asynchronous reset clears all

registers to a mid-scale code of 8000h or to a zero-scale

of 0000h. The DAC7664 can operate from a single +5V

supply or from +5V and −5V supplies.

Low power and small size per DAC make the DAC7664

ideal for automatic test equipment, DAC-per-pin

programmers, data acquisition systems, and closed-loop

servo control. The DAC7664 is available in an LQFP-64

package and is specified for operation over the −40°C to

+85°C temperature range.
