DAC7634E/1K集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC7634E/1K属于集成电路（IC）的数模转换器（DAC）。由德州仪器制造生产的DAC7634E/1K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 DAC7634 is a 16-bit, quad voltage output, digital·

to-analog converter with specified 15-bit monotonic

performance over the specified temperature range. It

accepts 24-bit serial input data, has double-buffered

DAC input logic (allowing simultaneous update of all

DACs), and provides a serial data output for

daisy-chaining multiple DACs. Programmable

asynchronous reset clears all registers to a mid-scale

code of 8000H or to a zero-scale of 0000H. The DAC7634 can operate from a single 5-V supply or

from 5-V and –5 V supplies.

Low power and small size per DAC make the

DAC7634 ideal for automatic test equipment,

DAC-per-pin programmers, data acquisition systems,

and closed-loop servo-control. The DAC7634 is

available in a 48-lead SSOP package and offers

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

range.
