DAC7641Y集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC7641Y属于集成电路（IC）的数模转换器（DAC）。由德州仪器制造生产的DAC7641Y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 DAC7641 is a 16-bit, voltage output digital-toanalog

converter (DAC) 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 asynchronous update), 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 DAC7641 can operate from a single +5V supply or

from +5V and –5V supplies.

Low power and small size per DAC make the DAC7641

ideal for automatic test equipment, DAC-per-pin

programmers, data acquisition systems, and closedloop

servo-control. The DAC7641 is available in a

TQFP-32 package, and offers guaranteed specifications

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