DAC7644EB集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC7644EB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DAC7644EB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 DAC7644 is a 16-bit, quad voltage output digitalto-

analog converter with guaranteed 15-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 zeroscale

of 0000H. The DAC7644 can operate from a single

+5V supply or from +5V and –5V supplies.

Low power and small size per DAC make the DAC7644

ideal for automatic test equipment, DAC-per-pin programmers,

data acquisition systems, and closed-loop

servo-control. The DAC7644 is available in a 48-lead

SSOP package and offers guaranteed specifications

over the –40°C to +85°C temperature range.
