DAC7625UB集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC7625UB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DAC7625UB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 DAC7624 and DAC7625 are 12-bit quad voltage

output digital-to-analog converters with guaranteed 12-

bit monotonic performance over the specified temperature

range. They accept 12-bit parallel input data, have

double-buffered DAC input logic (allowing simultaneous

update of all DACs), and provide a readback

mode of the internal input registers. An asynchronous

reset clears all registers to a mid-scale code of 800H

DAC7624) or to a zero-scale of 000H (DAC7625). The

DAC7624 and DAC7625 can operate from a single +5V

supply or from +5V and –5V supplies.

Low power and small size per DAC make the DAC7624

and DAC7625 ideal for automatic test equipment,

DAC-per-pin programmers, data acquisition systems,

and closed-loop servo-control. The DAC7624 and

DAC7625 are available in a 28-pin plastic doublewide

or a 28-lead SOIC package, and offer guaranteed

specifications over the –40°C to +85°C temperature

range.
