DAC7615U集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

DAC7615U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DAC7615U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 DAC7615 is a quad, serial input, 12-bit, voltage

output digital-to-analog converter (DAC) with guaranteed

12-bit monotonic performance over the –40°C

to +85°C temperature range. An asynchronous reset

clears all registers to either mid-scale (800H) or zeroscale

(000H), selectable via the RESETSEL pin. The

individual DAC inputs are double buffered to allow

for simultaneous update of all DAC outputs. The

device can be powered from a single +5V supply or

from dual +5V and –5V supplies.

Low power and small size makes the DAC7615 ideal

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

data acquisition systems, and closed-loop servocontrol.

The device is available in 16-pin plastic DIP,

16-lead SOIC, and 20-lead SSOP packages and is

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